The Anchorage

The Anchorage is an Italianate villa in Harmar featuring a distinctive campanile tower that overlooks Marietta and its two rivers. The mansion contains 22 rooms constructed with thick sandstone walls and locally sourced materials.

Douglas Putnam commissioned architect John Slocomb in 1859 to build this residence for his wife Eliza. The structure was constructed from locally quarried sandstone and oak materials, later becoming important to the Knox family's story.

The Knox family acquired the property in 1894 while they were involved in boat building and gave the mansion its current name. The name reflects the family's strong connection to river commerce and navigation.

The property sits in the Harmar Historic District and is maintained by the Washington County Historical Society with Hidden Marietta managing daily operations and tours. Visitors should check ahead since hours vary depending on the season.

The mansion's walls are 24 inches (61 centimeters) thick and were built from sandstone extracted from nearby hills, sitting on foundations carved directly from solid rock. This massive construction method made the building exceptionally durable and able to resist the effects of weather over many decades.
