In south-east London, Greenwich is the most historic of London't eight royal parks, dating back to Roman times and later a royal hunting park. Its 180 acres (74 ha) are part of the Greenwich World Heritage site that includes the Queen's House designed by Indigo Jones. On the top of the hill in the center is the Royal Observatory, home of Greenwich Mean Time (GMT). Summertime, it draws a large gay crowd.
