Built in 1828, The Arcade is the nation’s oldest existing indoor shopping mall and a National Historic Landmark. Designed by Russell Warren and James Bucklin, the architecture is notable due to two slightly different facades. Travel to the Weybosset Street side and you’ll find Warren’s design; six granite ionic columns rooted underneath a parapet. Venture to the Westminster side, and you’ll discover six ionic columns connected to a pediment, designed by Bucklin. Today the skylight-lit interior is home to shops, restaurants and residential housing in the form of micro-lofts.
