The extant medieval structures are largely private homes. The house featured in the image of Kings Head St to the left is unique in the town and is an example of a sailmaker's house, thought to have been built circa 1600. Notable public buildings include the parish church of St. Nicholas (1821) in a restrained Gothic style, with many original furnishings, including a somewhat altered organ in the west end gallery. There is also the Guildhall of 1769, the only Grade I listed building in Harwich.
