A structural survey was undertaken by Richard Shackle in 2007. 12-13 Trinity Street are a small two-storeyed building, with two bays and jettied onto Trinity Street. The front elevation has a carriage arch and the building was almost certainly built as a gatehouse, probably in the 15th century. By the 17th century it appears to have been converted into a house, shop or inn. There used to be a sign painted on the fascia board of the jetty saying that the building was once Fleur de Lys Inn. The extensions attached to the rear are of various dates, some dating back to the 17th century.<1>
