The main facade, built from red brick and Portland stone, stretches 720 feet (220 m) along Cromwell Gardens and was designed by Aston Webb after winning a competition in 1891 to extend the museum. Construction took place between 1899 and 1909. Stylistically it is a strange hybrid, although much of the detail belongs to the Renaissance there are medieval influences at work. The main entrance consisting of a series of shallow arches supported by slender columns and niches with twin doors separated by pier is Romanesque in form but Classical in detail. Likewise the tower above the main entrance has an open work crown surmounted by a statue of fame, a feature of late Gothic architecture and a feature common in Scotland, but the detail is Classical. The main windows to the galleries are also mullioned and transomed, again a Gothic feature, the top row of windows are interspersed with statues of many of the British artists whose work is displayed in the museum.
