The city is presently experiencing significant growth. As you drive around, you will notice evolving commercial and residential development. We are pleased that Sandwich is continuing to grow and develop, while yet retaining its historical heritage. The Sandwich city offices are located in an 1879 City Hall/Opera House. This building was completely restored in 1979 and is on the National Register of Historic Buildings.
