Trafalgar Cemetery
The cemetery was formerly known as the Southport Ditch Cemetery. It was consecrated in June 1798, seven years prior to the Battle of Trafalgar, which took place on 21 October 1805. The cemetery was sometimes considered to be part of St. Jago's Cemetery, the larger burial ground just to the north, on the opposite side of Charles V Wall. St. Jago's, also known as Deadman's Cemetery, was the only cemetery within the walls of the city of Gibraltar. In addition, it may have represented Gibraltar's oldest known cemetery. It was incorporated into St. Jago's Barracks playground in 1929, and repurposed as a rifle range and "ball alley." There exists little evidence of the former cemetery.
Trafalgar Square
In 1826 the Commissioners of H.M. Woods, Forests and Land Revenues instructed John Nash to draw up plans for clearing a large area south of Kent's stable block, and as far east as St Martin's Lane. His plans left open the whole area of what became Trafalgar Square, except for a block in the centre, which he reserved for a new building for the Royal Academy. The plans included the demolition and redevelopment of buildings between St Martin's Lane and the Strand and the construction of a road (now called Duncannon Street) across the churchyard of St Martin-in-the-Fields. The Charing Cross Act was passed in 1826 and clearance started soon after. Nash died soon after construction started, impeding its progress. The square was to be named for William IV commemorating his ascent to the throne in 1830. Around 1835, it was decided that the square would be named after the Battle of Trafalgar as suggested by architect George Ledwell Taylor, commemorating Nelson's victory over the French and Spanish in 1805 during the Napoleonic Wars.
After the clearance, development progressed slowly. The National Gallery was built on the north side between 1832 and 1838 to a design by William Wilkins, and in 1837 the Treasury approved Wilkins' plan for the laying out of the square, but it was not put into effect. In April 1840, following Wilkins' death, new plans by Charles Barry were accepted, and construction started within weeks. For Barry, as for Wilkins, a major consideration was increasing the visual impact of the National Gallery, which had been widely criticised for its lack of grandeur. He dealt with the complex sloping site by excavating the main area to the level of the footway between Cockspur Street and the Strand, and constructing a high balustraded terrace with a roadway on the north side, and steps at each end leading to the main level. Wilkins had proposed a similar solution with a central flight of steps. Plinths were provided for sculpture and pedestals for lighting. All the stonework was of Aberdeen granite. In 1841 it was decided that two fountains should be included in the layout. The estimated budget, excluding paving and sculptures, was £11,000. The earth removed was used to level Green Park. The square was originally surfaced with tarmacadam, which was replaced with stone in the 1920s.
