This landmark Continental Square building in York started as First National Bank in the 1920s. It weathered the Depression and then its signs changed several times over the years. Citizens Bank was the last shingle to hang there, removed in 2012. Now developer Derek Dilks is looking to give the building new life, planning a restaurant and apartments. That would represent a major change of life and activity to York’s main square, which has experienced much life and activity since the town was founded in 1741.
