Historic Environment Scotland in the context of "Non-departmental public body"

In the United Kingdom, a listed building is a structure of particular architectural or historic interest deserving of special protection. Such buildings are placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, Cadw in Wales, and the Historic Environment Division of the Department for Communities in Northern Ireland. The classification schemes differ between England and Wales, Scotland, and Northern Ireland (see sections below). The term has also been used in the Republic of Ireland, where buildings are protected under the Planning and Development Act 2000, although the statutory term in Ireland is "protected structure".

A listed building may not be demolished, extended, or altered without permission from the local planning authority, which typically consults the relevant central government agency. In England and Wales, a national amenity society must be notified of any work to be done on a listed building which involves any element of demolition.

The Antonine Wall (Latin: Vallum Antonini) was a turf fortification on stone foundations, built by the Romans across what is now the Central Belt of Scotland, between the Firth of Clyde and the Firth of Forth. Built some twenty years after Hadrian's Wall to the south, and intended to supersede it, while it was garrisoned it was the northernmost frontier barrier of the Roman Empire. It spanned approximately 63 kilometres (39 miles) and was about 3 metres (10 feet) high and 5 metres (16 feet) wide. Lidar scans have been carried out to establish the length of the wall and the Roman distance units used. Security was bolstered by a deep ditch on the northern side. It is thought that there was a wooden palisade on top of the turf. The barrier was the second of two "great walls" created by the Romans in Great Britain in the second century AD. Its ruins are less evident than those of the better-known and longer Hadrian's Wall to the south, primarily because the turf and wood wall has largely weathered away, unlike its stone-built southern predecessor.

Construction began in AD 142 at the order of Roman Emperor Antoninus Pius. Estimates of how long it took to complete vary widely, with six and twelve years most commonly proposed. Antoninus Pius never visited Britain, unlike his predecessor Hadrian. Pressure from the Caledonians probably led Antoninus to send the empire's troops farther north. The Antonine Wall was protected by 16 forts with small fortlets between them; troop movement was facilitated by a road linking all the sites known as the Military Way. The soldiers who built the wall commemorated the construction and their struggles with the Caledonians with decorative slabs, twenty of which survive. The wall was abandoned only eight years after completion, and the garrisons relocated rearward to Hadrian's Wall. Most of the wall and its associated fortifications have been destroyed over time, but some remains are visible. Many of these have come under the care of Historic Environment Scotland and the UNESCO World Heritage Committee.

Mons Meg is a medieval bombard in the collection of the Royal Armouries, on loan to Historic Environment Scotland and located at Edinburgh Castle in Scotland. It has a barrel diameter of 20 inches (510 mm), making it one of the largest cannons in the world by calibre.

Mons Meg was built in 1449 on the orders of Philip the Good, Duke of Burgundy, and sent by him as a gift to James II, King of Scots, in 1454. The bombard was employed in sieges until the middle of the 16th century, after which it was only fired on ceremonial occasions. In 1680 the barrel burst, rendering Mons Meg unusable. The gun remained in Edinburgh Castle until 1754 when, along with other unused weapons in Scotland, it was taken to the Tower of London. Sir Walter Scott and others campaigned for its return, which was effected in 1829. Mons Meg has since been restored and is now on display within the castle.

Historic Scotland (Scottish Gaelic: Alba Aosmhor) was an executive agency of the Scottish Office and later the Scottish Government from 1991 to 2015, responsible for safeguarding Scotland's built heritage and promoting its understanding and enjoyment. Under the terms of a Bill of the Scottish Parliament published on 3 March 2014, Historic Scotland was dissolved and its functions were transferred to Historic Environment Scotland (HES) on 1 October 2015. HES also took over the functions of the Royal Commission on the Ancient and Historical Monuments of Scotland.
