Sir Robert Lorimer was appointed in 1919. Construction began in 1923, and the memorial was formally opened on 14 July 1927 by the Prince of Wales. The exterior is decorated with gargoyles and sculpture, while the interior contains monuments to individual regiments. The stained-glass windows are by Douglas Strachan. The memorial commemorates Scottish soldiers, and those serving with Scottish regiments, who died in the two world wars and in more recent conflicts. Upon the altar within the Shrine, placed upon the highest point of the Castle Rock, is a sealed casket containing Rolls of Honour which list over 147,000 names of those soldiers killed in the First World War. After the Second World War, another 50,000 names were inscribed on Rolls of Honour held within the Hall, and further names continue to be added there. The memorial is maintained by a charitable trust. Present use Edinburgh Castle is in the ownership of the Scottish Ministers as heads of the devolved Scottish Government. The castle is run and administered, for the most part, by Historic Environment Scotland, an executive agency of the Scottish Government, although the Army remains responsible for some areas, including the New Barracks block and the military museums. Both Historic Environment Scotland and the Army share use of the Guardroom immediately inside the castle entrance. Tourist attraction Historic Environment Scotland undertakes the dual tasks of operating the castle as a commercially viable tourist attraction, while simultaneously bearing responsibility for conservation of the site. Edinburgh Castle remains the most popular paid visitor attraction in Scotland, with over 2.2 million visitors in 2019. Historic Environment Scotland maintains a number of facilities within the castle, including two cafés/restaurants, several shops, and numerous historical displays. An educational centre in the Queen Anne Building runs events for schools and educational groups, and employs re-enactors in costume and with period weaponry. Military role Direct administration of the castle by the War Office came to an end in 1905, and in 1923 the Army formally moved to the city's new Redford Barracks. Nevertheless, the castle continues to have a strong connection with the Army, and is one of the few ancient castles in Britain that still has a military garrison, albeit for largely ceremonial and administrative purposes. Public duties performed by the garrison include guarding the Honours of Scotland, and armed sentries stand watch at the Gatehouse outside opening hours. The post of Governor of
