Determining the oldest town in Scotland is subjective and depends on criteria such as continuous habitation, archaeological evidence, and historical significance. Musselburgh is often referred to as the oldest town in Scotland, but it's not the definitive oldest town in the country. Musselburgh has a long history with evidence of its existence dating back to Roman times, but there are other towns in Scotland that also have ancient origins such as Crail in Fife and the long-abandoned Skara Brae in Orkney.
