The close proximity to Circular Quay and the views of the iconic Harbour Bridge, as well as the historic nature of many of the buildings, makes the Rocks very popular with tourists. It features a variety of souvenir and craft shops, as well as many themed and historic pubs. The Rocks Market operates each weekend, with around 100 stalls. During the week, shopping options include galleries exhibiting Australian artists, such as Ken Done and Ken Duncan, as well as Australian clothing and Australian opal shops. There are numerous historic walks through the area, visiting historical buildings such as Cadmans Cottage and Sydney Observatory, and the Dawes Point Battery, which was the first fortified position in New South Wales.
