Developer Skanska has completed construction of a walking museum between its 101 and 121 Seaport office towers including historical exhibits on the neighborhood’s marine industrial past.

Skanska construction crews unearthed the remnants of a Colonial shipwreck in May 2016 while excavating the foundation of 121 Seaport, which is leased to the headquarters of Alexion Pharmaceuticals and software company PTC.

The interactive exhibits include a digital library of photos, maps and information on the history of the ship and the neighborhood, where tidal flats were filled during the 19th century to support the marine industrial trade. Skanska also developed a mobile app with augmented reality capabilities.

The museum is located on Harbor Way, a 70-foot-wide pedestrian path that runs between the two office towers and connects to WS Development’s neighboring parcels within the master-planned Seaport Square development.

“With each development we deliver, we aim to contribute to the public realm in a sustainable manner that respects the neighborhood in which we are working,” said Charley Leatherbee, leader of Skanska’s commercial development operations in Boston.
