A goat tower is a multi-story decorative goat house, modeled on a European garden folly, an early example of which was built in Portugal in the 19th century. The first goat tower was built at Aveleda, a winery in Portugal's Vinho Verde region. Since 1981, several other goat towers have been built in South Africa, Norway, Canada, the United States, the United Kingdom, and Argentina; these include three at other wineries. The towers typically are multi-story with climbing ramps spiralling the exterior and often become tourist attractions.
