Realizing the culturally significant neighborhood was at risk, Detroit's ethnic Greek leaders banded together. With the help of the Mayor's office, the streetscape and building exteriors were improved, and additional street lighting was installed. The neighborhood threw a Greek festival in 1966, timed to coincide with Fourth of July celebrations. The festival was a success, and was continued for years until turnout grew too large. By that time, Greektown was firmly established in Detroit. The Greektown Historic District was listed on the National Register of Historic Places in 1982.
