Visitors can apply for a maximum of two adult and three family tickets to each historic property of their choosing, including Dumbarton Castle, for Saturday November 28 or the following day. Family tickets admit up to two adults and three children.

There is no limit on the number of participating attractions that visitors can apply for tickets to but early online registration is being encouraged to avoid disappointment.

Stephen Duncan, Director of Commercial and Tourism for Historic Environment Scotland, said: “Our Ticket Giveaway weekend offers the public a fantastic opportunity to explore and discover more about some of the country’s best known heritage attractions, including its iconic castles, abbeys and palaces, amongst others, for free.

“This weekend-long event, which forms part of Scotland’s celebrations for St Andrew’s Day, sees thousands of tickets released for more than 30 of our historic sites participating in this year’s promotion.

“The Ticket Giveaway is always extremely popular with our visitors so we would encourage early pre-registration online through the Ticket Giveaway’s dedicated website so people don’t miss out on the chance to secure a ticket for the attraction of their choice.” Tickets can be applied for at www.ticketgiveaway.co.uk.
