This structure is proof that poor workmanship will defeat even great wealth. The 60-room Roman-style villa was built in 1905 by Alfred Mitchell to impress his sweetheart. Unfortunately, the concrete used to build it was mixed using seawater, which led to it disintegrating over time—the roof collapsed in 1935. Now the view of the harbor is worth more than the house, which is covered in graffiti and sometimes shelters vagrants: All that remains is the beautiful marble floor. East Harbour, Port Antonio.
