Stonehenge is a famous prehistoric monument and cultural heritage attraction, ranking as one of the most visited paid attractions in England and first for paid attractions in the South West of England. The monument is operated by English Heritage, the charity managing historic buildings, monuments and sites in England. Visitors to Stonehenge make up a significant proportion of the overall number of visitors to English Heritage staffed sites. Along with Avebury, Stonehenge forms a UNESCO World Heritage site.
Heritage sites are important cultural attractions in England, with around half of adults visiting a site at least once a year. Participation of children in heritage site visits is also relatively high due to family and school visits. In terms of inbound tourism, castles and historic houses are also key attractions for international tourists, particularly among older visitors. In 2015, historical sites, buildings and similar visitor attractions generated a turnover of around 468 million British pounds.
