The building that is called Winthrop House, at 166 Rowayton Avenue in Rowayton, Norwalk, was built in 1848 by Charles L. Raymond as a a four-story summer hotel. It has had many names, being called the Fairview Hotel by the turn of the century. It was a private home around the time of World War I, but then became a hotel again under various names over the years: Colonial Inn (1926), Pleasant Inn (1930) and Rowayton Inn (1935). During the Second World War it was purchased by the Bassler brothers. At the start of the twenty-first century there were plans to demolish the building, but in 2005 the Norwalk Preservation Trust worked with developer Andrew Glazer, the Rowayton Historical Society, the Rowayton Community Association and the Norwalk Planning and Zoning Office to restore the exterior to its nineteenth-century appearance. The interior was converted into three luxury condominiums.
