Maenza is a comune (municipality) in the Province of Latina in the Italian region Lazio, located about 70 km (43 mi) southeast of Rome and about 25 km (16 mi) east of Latina. It is home to a castle, originally built as a watchtower in the 12th-13th centuries, and enlarged in the 16th century. In an effort to bring in new residents, it is selling abandoned houses for €1 if buyers commit to renovations.[3]
