Castello di Santa Severa

Santa Marinella, Italy

Want to stay in a medieval castle for less than $50 per night? Look no further than this 14th century beachside citadel, which now functions as a hostel. The site—a short train ride from Rome—touts more than 2,000 years of fascinating history, with owners that ranged from the Catholic Church to Roman aristocracy. After four years of restoration, the castle and its adjacent buildings now function as a museum complex and hostel that sleeps 42. Despite the coastal grandeur, it is relatively low-frills: guests are responsible for seeing to their own breakfast in its communal kitchen. Visitors can explore the grounds, learn about ancient sea navigation or relax on the public beach beyond its walls. On Mondays, the castle is closed to the public—allowing hostel guests to roam free from crowds. —Wilder Davies
