8. St Margaret’s Chapel, Edinburgh Castle.
Thought to have been completed in 1130 by King David in honour of his mother, Queen Margaret, St Margaret’s Chapel has seen a fair few changes in Edinburgh. In fact, as the oldest building in the entire city, it’s seen all the changes. The chapel is situated within the walls of Edinburgh Castle, which may sound like a safe place to be until you consider that the castle has historically been the most besieged location in the whole of Britain. Once you factor in the Protestant Reformation of the 1500s and the fact that the chapel lay disused for centuries afterwards – save for a spell as a storage room for gunpowder – it’s actually quite incredible that it’s still standing. Today’s chapel has since been tastefully restored, first by Queen Victoria in the 1850s, who made it usable once more and reintroduced stained glass to its five windows, and again in 1922. Despite the rather compact little chapel only being able to hold around 20 people, modern weddings and baptisms are a regular occurrence at the 900-year-old place of worship.
