Mariner's Church greets you at 366–376 Fore Street in Portland, Maine. Built in 1828, this Greek Revival building once served as both a church and a marketplace and was for many years the city’s largest commercial building. It even survived the city’s great 1866 fire and was later listed on the National Register of Historic Places in 1973.
The building fills much of a city block here in the Old Port, on a trapezoidal lot bounded north by Fore Street, east by Market Street, and west by Moulton Street, its main facade facing toward Fore Street. It is a three‑story masonry structure of granite and brick, with a broad gabled roof. Look at the ground level: six storefronts, each with a recessed entrance and a large fixed‑pane display window to one side.
Above them a bank of twelve round‑arch windows gives the second floor a rhythmic sweep, with simple rectangular windows on the third. The gable is fully pedimented, a fanlight set near the center of its base, and the building’s corners are rounded. Notice the pedimented gable ahead, then follow Fore Street to where Market meets Moulton.
