Marlipins Museum, is a 12th to early-13th century Grade II* listed building on the High Street in Shoreham-by-Sea, a town in Adur district in West Sussex, England. It is distinguished by its chess-board pattern of stone flint on its frontal façade.
The initial estimate of the date of the building is thought to be 12th century based on new evidence which has emerged following the demolition of the adjunct building during the construction of the new annexe. The northern wall was originally constructed between 1167 and 1197 and that this was demolished and replaced by a new wall in the 15th century. It is thought to be the oldest complete non-religious building in Britain.
The Caen stone frontage is thought to have been added in the late-13th to early-14th century along with other renovations. Repairs and reconstruction then took place to the roof in the 15th century and new internal timbers were installed in the 16th century.
