context_page_description: Edinburgh Castle is a historic fortress which dominates the skyline of Edinburgh, the capital city of Scotland, from its position on the Castle Rock. Archaeologists have established human occupation of the rock since at least the Iron Age, although the nature of the early settlement is unclear. There has been a royal castle on the rock since at least the reign of David I in the 12th century, and the site continued at times to be a royal residence until 1633. From the 15th century, the castle's residential role declined, and by the 17th century it was principally used as military barracks with a large garrison. Its importance as a part of Scotland's national heritage was recognised increasingly from the early 19th century onwards, and various restoration programmes have been carried out over the past century and a half. As one of the most important strongholds in the Kingdom of Scotland, Edinburgh Castle was involved in many historical conflicts from the Wars of Scottish Independence in the 14th century to the Jacobite rising of 1745.
context_section_description: The Half Moon Battery, which remains a prominent feature on the east side of the castle, was built as part of the reconstruction works supervised by the Regent Morton, and was erected between 1573 and 1588. The Forewall to the north was built between 1689 and 1695 to link the Half Moon to the Portcullis Tower, although part of the original wall of 1540 was incorporated into it. The Half Moon Battery was built around and over the ruins of David's Tower, two storeys of which survive beneath, with windows facing out onto the interior wall of the battery. David's Tower was built on an L-plan, the main block being 51 by 38 feet (16 by 12 m), with a wing measuring 21 by 18 feet (6.4 by 5.5 m) to the west. The entrance was via a pointed-arched doorway in the inner angle, although in the 16th century this was filled in to make the tower a solid rectangle. Prior to the Lang Siege, the tower was recorded as being 59 feet (18 m) high, and the remaining portions stand up to 49 feet (15 m) from the rock.
  The tower was rediscovered during routine maintenance work in 1912, and excavations below the Half Moon Battery revealed the extent of the surviving buildings. Several rooms are accessible to the public, although the lower parts are generally closed. Outside the tower, but within the battery, is a three-storey room, where large portions of the exterior wall of the tower are still visible, showing shattered masonry caused by the bombardment of 1573. Beside the tower, a section of the former curtain wall was discovered, with a gun loop which overlooked High Street: a recess was made in the outer battery wall to reveal this gun loop. In 1912–1913 the adjacent Fore Well was cleared and surveyed and was found to be 110 feet (34 m) deep, mostly hewn through the rock below the castle.
