 Modern civil architecture appeared in Bermuda in the 1960s, though it has been mostly limited to the city of Hamilton and its immediate outskirts.Generally used for private commercial purposes, the overseas styles began to take over the Hamilton skyline as international business grew, restricted only by a government mandate that no building be taller than the city's Cathedral.In 2000, the Town of St. George and the east-end fortifications were nominated for inclusion on UNESCO's list of World Heritage Sites, under the grounds of architecture that illustrates human history (criterion iv) and direct association with events and traditions (criterion vi).
