From the Castle Esplanade, the first building on the right is [[Cannonball House (Edinburgh)|Cannonball House]] which has a cannonball lodged in the wall facing the Esplanade, often said to have been accidentally fired from the Castle but which actually marks the elevation of Comiston Springs, three miles to the south of the Castle, which fed a [[cistern]] on Castlehill, one of the first piped water supplies in Scotland.<ref>{{cite web | url = https://canmore.org.uk/event/590536/ | title = Civil Engineering Heritage....... | access-date = 2023-05-21}}</ref>

Castlehill is dominated by the former Tolbooth-Highland-St John's Church (on the south side at the foot of this section), now the headquarters of the [[Edinburgh International Festival]] society – [[The Hub (Edinburgh)|The Hub]], and on the north side by the [[Outlook Tower|Outlook Tower and Camera Obscura]]. The [[General Assembly Hall of the Church of Scotland|Assembly Hall]] of the [[Church of Scotland]] and [[New College, Edinburgh|New College]] are further down on the same side. The [[Scottish Parliament]] met in the Assembly Hall between 1999 and 2004.
