The mansion was built during the decade of 1660 by a well-known English merchant in Zakynthos, Robert John Geoffrey. It was bought by Alexander Roma in 1880 and since then it belongs to the family. The house beyond its historical significance to the modern history of the island, it also represents the only sample of the large urban mansion-house, left intact in Zakynthos after the earthquake of 1953. Indoors, visitors can see furniture, a collection of family portraits, paintings, uniforms and arms of family members, and other historical objects. There is also a rich library (over 10,000 titles), consisting of very old and rare editions, starting from the 16^th century until today.
