Trams were part of the city's transport system until 1954 and today these heritage trams have been beautifully restored, offering visitors a unique experience that takes one on a two-mile (3km) loop of many of the city's best features and main attractions. The drivers, who offer insight on the history, architecture, activities and points of interest, supply informative and entertaining commentary. Visitors can hop on and off at any of the stops to further explore the attractions at leisure. The most interesting sights include the Aquarium of Discovery, punting on the Avon River, the exquisite Botanic Gardens on the banks of the river, New Regent Street with its pretty Spanish mission-style architecture, the magnificent Gothic buildings of the Arts Centre, and Canterbury Museum, with an excellent Antarctic exhibition. The Christchurch Tramway was damaged in the 2011 earthquake and was closed for repairs for some time, but reopened for service in November 2013.
