Crichton
Crichton is a toponym and surname of Scottish origin. The place name first appears in records of the parish of Penicuik in Midlothian, where the small settlement of Crichton was situated near the former Crichton estate. The most prominent landmark associated with the name is Crichton Castle, a 15th‑century tower house built by William Crichton, a royal favourite and later Lord High Chancellor of Scotland. The castle was expanded in the following centuries and served both as a defensive stronghold and a noble residence. Although now largely in ruins, it is a scheduled monument and an example of late medieval Scottish architecture. The surrounding estate was historically significant for its quarrying and ironworks, which contributed to the local economy during the 16th and 17th centuries.
