Union Trust Building

Although a “groundbreaking” ceremony for the start of one of downtown Cleveland’s largest-ever building renovations may not happen until late summer, you may see work crews going in and out of the former Union Trust Bank, 925 Euclid Ave., even earlier. That’s because an interior demolition permit application was submitted to the city this week to prepare for construction work in converting the 1.4-million-square-foot behemoth into The Centennial, featuring nearly 600 apartments, 170 hotel rooms, plus retail, restaurants and a museum.
