Aberdeen Pavilion

The Aberdeen Pavilion is a historic exhibition hall in Lansdowne Park in Ottawa, designated a National Historic Site in 1983 and a protected heritage building in 1984. Built in 1898, the structure originally housed the annual agricultural fair and was named after the governor general at the time. Thanks to its elegant architecture, it earned the nickname "Cattle Castle." The pavilion is also known as the oldest surviving venue to have hosted Stanley Cup games, as hockey matches were played here in 1904. After facing the threat of demolition in the 1990s, the building underwent a comprehensive restoration and is now considered one of the most beautiful places in the city.
