Queensferry (often referred to as South Queensferry to distinguish it from North Queensferry), originally a Royal Burgh in West Lothian, is now part of the City of Edinburgh, Scotland. It is located some ten miles to the north west of the city centre, on the shore of the Firth of Forth between the Forth Bridge and the Forth Road Bridge, approximately 8 miles (13 km) from Edinburgh Airport. The town's population is around 12,000 people. The older Scottish Gaelic name is Cas Chaolas meaning "Steep Sided Strait".
The town is named after Saint Margaret of Scotland who is believed to have established a ferry at this point for pilgrims on their way north to St Andrews. She died in 1093 and made her final journey by ferry to Dunfermline Abbey. Her son, David I of Scotland, awarded the ferry rights to the abbey.
There had been ferries at South Queensferry until 1964 when the Forth Road Bridge was opened. Ferry services continue to run from the harbour to the islands within the Firth of Forth, including Inchcolm.
