Edinburgh Castle

A must in Edinburgh is a visit to the well preserved Edinburgh caste on top of the hill, dominating the city. It housed the Royal family until the siege in the 1570s. A visit to the castle with its gatehouses, caste walls, terraces, compartment with relics and good views of the city will cost you a few hours at the least. There are some good audio tours that give a vivid background story while exploring the grounds.
