Town Hall is getting a new name.

Smithtown officials will gather alongside the Smithtown 350 Foundation on Sunday, Nov. 1, at 1 p.m., to officially dedicate the town hall building to Supervisor Pat Vecchio (R) — the longest serving supervisor in the history of the state. The dedication has been months in the making since the Town Board voted unanimously in March to dedicate the building in Vecchio’s honor after his nearly four decades of public service to the township.

As part of the town’s 350th birthday this year, Smithtown has been buzzing with activity since the beginning of 2015 with various events celebrating the town’s storied past. The town’s official 350th birthday was March 3, the same day the Town Board caught Vecchio off guard by voting to dedicate the building to him. The resolution that council members voted upon was signed and placed in a time capsule that will be buried near Town Hall this year.

Vecchio has served as supervisor since 1978 and also served in the U.S. Army during the Korean War, before an honor-able discharge in 1954, when he joined the New York Police Department, where he remained for 20 years, the resolution said. His NYPD roles included detective sergeant, chief of security for former Mayor John Lindsay and a member of a special unit responsible for the protection of visiting dignitaries, including former presidents Dwight D. Eisenhower and John F. Kennedy.

A reception will also immediately follow the event inside Town Hall.
