The old town is centred on the marketplace and the adjoining streets of Bridge Street, Wrawby Street, and Bigby Street. The marketplace and Wrawby Street, where much of the town's retail is located, were pedestrianized in the early 1990s. A significant number of buildings in the town centre date to the late 1700s or early 1800s and are listed, with the old town as a whole designated a Conservation Area. The marketplace is dominated by the Buttercross and the Angel, a former coaching inn with an early mock Tudor façade, which is now home to Brigg Town Council and various North Lincolnshire Council services. Another former coaching inn, the Exchange, stands in Bigby Street, opposite the former manor house of the Elwes family. The Anglican church of Saint John the Evangelist, built in 1843, also lies on Bigby Street. Its style is of the Gothic Revival architecture popular at the time, but Pevsner notes the curious construction where the stone has first been carved into the shape of bricks before being laid in courses.
