The Wheeler Block, also known as the Old Town Hall and the former Ransom School, is a historic civic and commercial building at 40 Norwich Avenu in Colchester, Connecticut. It is a 2-1/2 story wood frame structure in the Second Empire style, with a mansard roof, bracketed cornice, and gable-roof dormers with paired round-arch windows. It was built in 1872 by Joshua Wheeler, a local merchant and Mason. The building originally housed commercial businesses in the ground floor and the local Masonic lodge above. In 1910 Wheeler's daughter gave the building to the town, which used it as a schoolhouse until 1936, and as town hall until 1991.
