The now-ruined Church of St. Assam, locally known as "the old Protestant church", was rebuilt in 1712 on the site of "the parochial church dedicated to St. Assam", according to a dedication stone in the wall. It was a simple structure, 16.25 m by 7.15 m externally (with walls 0.75 m thick), and a mid-19th century plan shows a porch at the west end and a vestry at the east end of the north side, with internal arrangements for 116 worshippers. The porch is described in the Parliamentary Gazetteer as having a flat bell turret while the still-high east gable had a large window with tracery. Rectangular sockets on the walls may have been used to hold wooden panelling prior to the closure of the church in 1889, following the building of All Saints Church a few hundred metres citywards.
