Marietta is a small borough of about 2,600 on the western bank of the Susquehanna River in Lancaster County, Pennsylvania. The community is one of the best-preserved historic river towns in the state, with blocks of 18th and 19th-century stone and brick buildings along Front Street and Market Street. The town was once a bustling river port and iron-making center, and that industrial heritage is visible in the architecture and layout. Today, Marietta attracts a mix of long-time residents, history enthusiasts, and creative types drawn to the character of the buildings and the affordability compared to nearby communities like Columbia and Lancaster city. The Susquehanna River provides a scenic backdrop and recreational opportunities — fishing, kayaking, and the Northwest Lancaster County River Trail are popular. Donegal School District serves local students. Most daily necessities require a short drive to Columbia (about 3 miles south) or the Route 30 commercial corridor. The commute to Lancaster city takes about 20 minutes, while Harrisburg is about 30 minutes northwest via Route 283. Housing stock consists primarily of older row homes and detached homes, many with historic character and affordable price points. The Marietta Restoration Associates has worked to preserve the town's historic fabric, and several antique shops, galleries, and small businesses give the Main Street area a distinct artistic identity. Flooding from the Susquehanna is a periodic concern, and buyers should check flood maps carefully.
