Do not miss Lowell Walks this week with former state Sen Steve Panagiotakos leading a tour through the Greek-American territory in the Acre, from Dutton Street Demosthenes Club over to the Holy Trinity Church, first Byzantine-style church in the U.S., and important locations in between covering patriotic, cultural, business, political, and spiritual history. Meet this Saturday, 10 AM, at Lowell National Historical Park Visitor Center, 246 Market St. (photo courtesy of Holy Trinity Church website)
