The castle is the number one paid-for visitor attraction in Soctland, and last year for the first time, over two million people visited, a record 15% increase on the previous year.

The castle has been nominated for a BTA before and previously won four times in a row, between 2011 and 2014.

Nick Finnigan, Edinburgh Castle executive manager, said: “This nomination is a huge vote of confidence in Edinburgh Castle’s high-quality exhibitions, fascinating history, professional staff and incredible views of the city.”

He said: “If we were to win, this award would build on a fantastic year for the castle – we have experienced another record-breaking season, with more people coming through the castle gates than ever before.

“We are so grateful to all our wonderful visitors and we thank them for their continued support.

He added: “We’re up against some stiff competition in the Best UK Leisure/Heritage Attraction category and we ask our visitors to vote for Edinburgh Castle to win.”

The BTAs are the largest and most influential poll of consumer opinion on the performance of leisure travel and tourism providers.
