The Classic tour winds through the old town which is the oldest part of the designated UNESCO world heritage site. It starts at Edinburgh castle which sits high above the city centre on castle rock. This dramatic rock has sheer drops falling down to Princes Street Gardens. Stretching downhill from the castle is the famous Royal Mile along which are some of the oldest buildings in Edinburgh. The John Knox house for example, dates back to 1470. The tour takes you along all the different sections of the Royal Mile which are Castlehill, Lawnmarket, High Street and Canongate. All the way along the street are numerous wynds, closes and courts which you will be able to explore and learn about. All have been preserved or restored and the buildings within them have differing uses. Some contain thriving shops, restaurants while others remain as living quarters. One building which you will see along the mile is the impressive St Giles High Kirk (Cathedral) which was founded in the 1120s. Towards the foot of the mile is the Canongate. The origin of this is word is Canon gait (or walk). This is where the clergy used to walk to Holyrood Abbey, the ruins of which can be found at the end of the mile. The Abbey is situated next to the Palace of Holyroodhouse, which is the official residence of the Queen when she visits Edinburgh. The tour will end here at the Palace and next to the Scottish Parliament both of which you will learn about on the tour.
