Metro South Historic District

The Metro South Historic District encompasses a portion of the downtown area of Middletown, Connecticut. Extending south from Main and College Streets for two blocks, this area was developed in the 19th century, and contains a diversity of well-preserved architecture from that period, some with association to locally important individuals. It was listed on the National Register of Historic Places in 1980.

Description and history
The district includes 15 contributing buildings and one non-contributing building and extends on the west side of Main Street from Church Street (just north of the South Green) to College Street. Two buildings, the armory and a c. 1750s colonial house, are located on the east side of Main Street. The contributing buildings include two Greek Revival churches: a Baptist church (1842) and Universalist Church (1839). One of the buildings, the Middlesex Opera House was designed by nationally known architect Francis Kimball.

The southern part of Middletown's Main Street was predominantly residential into the 19th century, and still includes a few houses from the colonial and Federal periods. In the late 19th century, the commercial portion of the downtown began to extend southward, as exemplified by the construction of the opera house 1892 and the armoury in 1921. Other buildings of note from that period are the 1896 firehouse, and the 1867 Middlesex Assurance Company building at 179 Main Street, which is one of the district's most architecturally sophisticated buildings.
