View across Trafalgar Square, City of Westminster, looking east from Pall Mall East along the northern side of the square (this is now pedestrianised). Trafalgar Square was planned as part of the redevelopment of the West Strand Improvements by John Nash following the passing of the Charing Cross Act of 1826. Although it was to be another 30 years before the square was completed, it occupies the area of the former Great Mews of the Crown Stables. Charles Barry was the architect, although he opposed the decision to erect Nelson's Column on the site - he was overruled. The whole square is Grade I listed, number 1001362. To the left is The National Gallery built 1832-38 by William Wilkins, to house The Angerstein Collection of paintings purchased by the government for The Royal Academy. The central Corinthian portico is raised on a podium wall with flanking steps and set back behind the portico pediment is a stone cupola dome. The secondary Corinthian porticoes have parapets raised over a central bay. The terminal pavilions have pairs of giant pilasters surmounted by small octagonal stone cupolas with pierced work openings. It is Grade I listed, number 1066236. On the northeast corner of the square is the church of St Martin-in-the-Fields. The earliest reference to the church is from 1222, and Henry VIII rebuilt it in 1542 to keep plague victims in the area from having to pass through his Palace of Whitehall. By 1710 the walls and roof were in a state of decay, and in 1720, Parliament passed an act for the rebuilding of the church allowing for a sum of up to £22,000, to be raised by a rate on the parishioners. The current church was built 1722-26 to a neoclassical design by James Gibbs in Portland Stone with a staged tower and steeple rising above a Classical Corinthian portico. It is Grade I listed, number 1217661. In the street is a horse-drawn omnibus, a Hansom cab, and other horse-drawn carts.
