Harwich is a town in Essex, England and one of the Haven ports, located on the coast with the North Sea to the east. It is in the Tendring district. Harwich today is contiguous with Dovercourt and the two, along with Parkeston, are often referred to collectively as Harwich. Despite, or perhaps because of, its small size Harwich is highly-regarded in terms of architectural heritage, and the whole of the older part of the town, excluding Navyard Wharf, is a conservation area. The extant medieval structures are largely private homes. Notable public buildings, all later, include the parish church of St. Nicholas (1821) in a restrained Gothic style, with many original furnishings including a (somewhat altered) organ of the same date in the west end gallery, and the Guildhall of 1769, the only Grade I listed building in Harwich
