St. Phillip's Church

Chalmers Street is one of Charleston’s most iconic thoroughfares, renowned for being one of the few remaining streets in the city paved entirely with historic cobblestones. Originally known as Beresford’s Alley, this street features Bermuda limestone "cobbles" that were brought over by sailing ships during the 18th century. These stones served as ballast to stabilize vessels on their transatlantic journeys; once the ships reached Charleston’s harbor to load up with rice and indigo, the stones were discarded on the docks and later repurposed to pave the city’s marshy, low-lying streets. 

The Pink House, located at 17 Chalmers Street, is one of the oldest residential structures in Charleston, dating back to the late 17th or early 18th century. Constructed of pinkish-hued Bermuda stone—a soft coral limestone brought to the city as ballast on trading ships—the building is a rare example of a "gambrel-roofed" structure in the French Quarter. Its petite footprint, originally consisting of only one room per floor across three stories, reflects the early colonial architectural style of utilizing narrow lots for combined residential and commercial purposes. Situated near attractions such as the Dock Street Theatre and the French Huguenot Church, the house has served various roles over its long history, from a private tavern for sailors and merchants to a law office and an art gallery.

The Old Slave Mart Museum on Chalmers Street was built in response to a 1856 city ordinance that banned the public auctioning of enslaved people. Before this ordinance, auctions were held outdoors, often on the north side of the Custom House or near the Exchange Building. As Charleston sought to project an image of 'refinement' and urban order, city officials deemed these public sales a 'nuisance' and moved the domestic trade behind closed doors. By the time the Mart was constructed, the international slave trade had been banned for over 50 years (since 1808), leading to a shift toward the domestic slave trade where individuals were 'sold south' from states like Virginia and Maryland to the expanding cotton and rice plantations of the Deep South. 

DuBose Heyward was an essential figure of the Charleston Renaissance, best known for writing the 1925 novel Porgy, which George Gershwin later adapted into the world-famous opera Porgy and Bess. Born in 1885 to an aristocratic family that had fallen into poverty, Heyward worked as a cotton checker on the Charleston waterfront, where he became fascinated by the Gullah culture that inspired much of his writing. His residence from 1919 to 1924, known as the Dubose Heyward house at 76 Church Street, is a modest two-story stuccoed structure where he penned the works that pioneered a more humanized and respectful depiction of Southern African Americans in literature. Visitors on a Charleston architecture tour can appreciate this historic site, which is near landmarks such as the Dock Street Theatre and the French Huguenot Church. Although the building was declared a National Historic Landmark in 1971, it has since been significantly altered and now serves as an attached wing to the larger three-story house at 78 Church Street.

The design of the Charleston single house is a hallmark of Charleston architecture, characterized by its narrow, rectangular form that is only one room wide, with its gabled end facing the street. This unique orientation allows the house to extend deep into its lot, featuring a central staircase hall that typically separates two main rooms on each floor. A defining element is the piazza, a long, shaded porch running the length of the building’s side. The street-facing door is often a 'false door' or privacy screen that opens onto this piazza, while the actual entrance to the interior is located halfway down the porch, discreetly tucked away from public view. This single-room width facilitated effective cross-ventilation, allowing breezes to flow directly through windows on both sides of a room. Builders frequently oriented the piazzas toward the south or west to capture the prevailing summer winds from the harbor, providing deep shade that kept interior rooms significantly cooler before the advent of air conditioning. The roots of this design can be traced back to Barbados, a sister colony whose settlers founded Charleston in 1670. Features such as the side-facing veranda and slender profile were practical tropical building techniques employed in Bridgetown to withstand the intense sun. 

Founded in 1682 by settlers fleeing religious persecution in Maine, Charleston's First Baptist Church is the oldest Baptist congregation in the South. Its current sanctuary, completed in 1822, was designed by Charleston native Robert Mills, the first American-born professional architect and the designer of the Washington Monument. Mills described this Greek Revival masterpiece as the city's finest example of 'correct taste,' featuring a grand Doric portico and an interior optimized for acoustics and visibility, setting a new standard for American church architecture. This building is a highlight on any Charleston architecture tour, serving as a testament to Mills’ obsession with permanence and functional design, traits also seen in his nearby Fireproof Building. Under the leadership of Pastor Richard Furman, the church became a pivotal site for the formation of the Southern Baptist denomination. Today, the sanctuary remains a National Historic Landmark, housing significant artifacts like a solid mahogany pulpit from 1822 and a rare 1845 Erben organ, preserving the legacy of both the congregation and its famous architect. 

The James Simmons House, located at 37 Meeting Street, is a prominent late 18th-century residence that exemplifies the density and evolution of downtown Charleston’s historic architecture. Believed to have been constructed circa 1760 for James Simmons, a local lawyer, the home is situated on Lot 278 of the Grand Model of Charles Town, one of the earliest urban plans in the British colonies. Structurally, the residence was built as a traditional Charleston double house, featuring a formal Georgian floor plan with a central hallway dividing four principal rooms on each floor, all supported by solid brick exterior walls measuring nearly two feet thick.

Beyond its structural significance, the property has a history marked by wartime occupations and notable regional figures.Following Simmons's death in 1775, the home became the residence of Governor Robert Gibbes, whose family was forced to evacuate the property when British forces occupied Charleston during the Revolutionary War; they later returned to find the structure heavily damaged. In subsequent decades, the house passed to other high-profile owners, including Otis Mills, the prominent financier and owner of the nearby Mills House Hotel, who purchased the property in the 1840s. During the Civil War, the residence served a strictly utilitarian military purpose when it was loaned to Confederate General P.G.T. Beauregard, who utilized the strategic Meeting Street location as his official executive headquarters from October 1862 until August 1863.

The physical appearance of the house underwent permanent alterations that reflect the shifting architectural trends of the 19th century. Originally constructed with a flat facade, the front of the building was significantly modified during Otis Mills's ownership with the addition of twin two-story bay windows that curve symmetrically out over Meeting Street.These projecting bays are connected on the second story by an intricate, heavy cast-iron balcony, a design element that sets it apart from more conventional double houses in the neighborhood. In the modern real estate era, the expansive double-lot property, which covers roughly a third of an acre and includes an attached carriage house and wine cellar, has continued to set precedents, repeatedly breaking records as one of the most expensive residential sales in the historic district.

The "Three Sisters" of Charleston, located at 101, 103, and 105 Meeting Street, represent one of the city's most visually distinct and frequently photographed architectural groupings. Situated just south of Broad Street, these three adjacent, narrow residences present a striking uniform density on the streetscape, defined by their pastel-colored stucco facades, contrasting dark shutters, and closely aligned footprints. Despite local folklore suggesting they were built by a wealthy father for his three daughters, historical records reveal a much more practical and commercial origin.

The properties were actually developed in the mid-19th century by a single investor, a factor that accounts for their shared architectural rhythm. They are designed as classic Charleston "single houses," a regional layout where the narrow end of the structure faces the street directly to maximize property tax efficiency and capture prevailing coastal cross-breezes. While they share a common orientation and scale, close inspection reveals distinct individual variations in their rooflines and decorative detailing—ranging from gabled roofs to differing styles of ironwork on their small second-story balconies.

Today, the Three Sisters stand as a premier example of how Charleston’s historical preservation efforts have maintained the structural scale of the historic district. Their tightly clustered presentation highlights the high-density urban planning characteristic of the city's early development, where residential estates were continually subdivided to accommodate a growing merchant class. The houses remain private residences, serving as a landmark anchor along the lower Meeting Street corridor.

Water Street is a short, historic thoroughfare in downtown Charleston's South of Broad neighborhood that directly reflects the physical transformation and engineering history of the peninsula. Running east from Meeting Street down to East Battery, the street does not follow a standard colonial grid layout because it was not originally dry land. Instead, it follows the precise path of Vanderhorst’s Creek, a deep, tidal saltwater stream that once cut into the peninsula and separated Church Street from the southern tip of White Point. 

In the 18th century, the creek served as a natural boundary and was managed by a system of earthen fortifications and a 30-foot-wide tidal canal with a floodgate near the modern East Battery intersection.

The conversion from a waterway to a residential street occurred gradually between the late Revolutionary War era and the early 19th century. Following severe storm damage from the Great Hurricane of 1752 and subsequent urban fires, city commissioners and local property owners systematically confined and filled the creek bed with earth, ballast stone, and rubble to create new, high-density building lots for the expanding merchant class. 

By the 1780s, the western section between Meeting and Church streets was officially recognized as Water Street, though the easternmost blocks remained a tidal canal dry only at low tide until the completion of the permanent East Battery seawall in the 1810s.

Because of its origins as a low-lying creek bed, the street contains distinct architectural adaptations designed to mitigate the Lowcountry's chronic water levels. Notable structures along the corridor, such as the Federal-style Francis Saltus House at 6 Water Street (built circa 1820) and the Italianate residence at 1 Water Street (built 1857), feature raised brick basements and elevated living quarters. In the modern era, the street has served as a testing ground for advanced preservation engineering; for instance, the historic brick structure at 1 Water Street became the first historic brick property in the district to be mechanically elevated eight feet off the ground to eliminate modern flood risk while maintaining its placement on the historic streetscape.
