caption_attribution_description: English: Extract from "a Survey of the City, Harbour, Bay and Environs of Dublin on the same Scale as those of London, Paris &amp; Rome". A map of Dublin by John Rocque (1709–1762) which is dated to 1757 . This extract highlights the area of the Phoenix Park in Dublin, immediately to the north of IslandBridge. The two principle subjects of this extract are: An earthen-works star fort (labelled "The Fortification" centre/top) - This fortification was commissioned by then Lord Lieutenant of Ireland Thomas Wharton (1648-1715) and designed by Thomas Burgh (1670–1730). Construction started in 1710, but the fortification was never completed. Note the incomplete section/gap on the north east "corner". The remaining earth-works were demolished in 1837.[1] A brick and limestone bastion fort (Labelled "Powder Magazine" centre-left/bottom) - This fortification was commissioned by then Lord Lieutenant of Ireland Lionel Sackville (1688-1765) and designed by John Corneille. Construction started in 1734/1735. The resulting Magazine Fort still stands in Dublin's Phoenix Park
context_page_description: The Magazine Fort is a bastion fort and magazine located within the Phoenix Park, in Dublin, Ireland. Built in 1735, it was occupied by British Armed Forces until 1922 when it was turned over to the Irish Defence Forces after the Anglo-Irish Treaty. The Irish Army continued to operate the site as an ammunition store through the mid-20th century. It was fully demilitarised by the 1980s. The fort is now managed by the Office of Public Works. As of 2015, it was in a derelict state and not open to the public, however some repairs were undertaken and the site partially opened for "limited guided tours" from 2016.
context_section_description: Unlike de Burgh's nearby star fort, which was primarily earthwork and demolished in the 1830s, Corneille's bastion fort was built of brick and limestone.
  The main body of the fort is approximately 2 acres in area and is surrounded by a dry moat. Each corner is defended by a demi-bastion (with embrasures), and the walls are approximately 1.5 metres (5 ft) thick. The large barrel-vaulted brick magazine chambers themselves are approximately 270 square metres (2,900 sq ft) in size and located to the north-west of the main enclosure. These were serviced by overhead cranes and gantries – for moving powder kegs. A later triangular barracks and accommodation block was added on the south-side in 1801, to designs by Francis Johnston. Other sheds and outbuildings were added in the 20th century.
