Craigmillar Castle sits on the outskirts of Edinburgh as Scotland's historic retreat castle, gaining prominence when Mary, Queen of Scots sought refuge there in 1566. Featuring one of Scotland's oldest tower houses with a fine great hall and prison, the castle offers visitors panoramic views across Edinburgh from its rooftop walkway, including vistas toward Holyrood Park and Edinburgh Castle. Notable features include a distinctive P-shaped fishpond representing the owner Sir Simon Preston's name. The castle serves as a wedding venue and has gained cultural significance through appearances in television productions including *Outlander* and *Outlaw King*, while undergoing ongoing conservation efforts managed by Historic Environment Scotland.
