Caerlaverock is unusual both for its triangular design and its pink limestone. Both make it quite a striking sight (see photographs). The castle is technically ruined, but the two front-facing walls and most of the rest of the superstructure remain intact. There is a classic moat surrounding the building, and a narrow wooden bridge gives access to the main gate.
Like Dryburgh Abbey, this property is administered by Historic Scotland, so the grounds have been landscaped and the interior courtyard paved and gravelled, with railings added in spots. It's fun to climb around inside the towers and interior buildings, which are labelled to explain their original purpose and use. Like many castles, different portions date from various eras, so the design is a bit of a jumble. The main attraction is a 17th-century residence, with servery, kitchen, and private rooms. On the opposite side is a 15th-century structure which apparently contained a great hall and other residences. The two towers bestride the main gate were used as lord's residences in the 13th and 14th centuries.
One interesting bit of history: in 1300, Edward I himself, with a 3000-man army, besieged the castle. The garrison of only sixty men held out for 36 hours. When Edward learned how few his enemy had been, he was so impressed that he allowed the Maxwell family to keep the castle after swearing an oath of loyalty to him.
As wonderful as the castle is, the visitor's centre boasts a "museum" which is nothing but a sad joke. Breeze through it, just enough to get the story of the castle, the Maxwells, and the various military actions over the years, and then get right out onto the grounds. There is also a "nature trail" which leads about 200m to the site of the previous castle, used for only a few decades in the mid-13th century and abandoned due to the marshy ground (Caerlaverock is very near the Solway Firth).
There are picnic tables, and on a day with good weather, this would be a great site to bring the family for an afternoon.
