Located just 30 minutes from Edinburgh, Scotland, this 600-year-old castle is known to locals as “Scotland’s greatest keep,” perhaps due to its magnificent and historical design. Built from 30,000 tons of ashlar stone, Borthwick Castle is one of Scotland’s largest and most well-preserved medieval fortifications, and wedding celebrations here are completely bespoke. As an added bonus for history buffs, the castle has been hosting weddings since 1458.
