The English contribution to Romanesque art and Gothic art was considerable, especially in illuminated manuscripts and monumental sculpture for churches, though the other countries were now essentially provincial, and in the 15th century Britain struggled to keep up with developments in painting on the Continent. A few examples of top-quality English painting on walls or panel from before 1500 have survived, including the Westminster Retable, The Wilton Diptych and some survivals from paintings in Westminster Abbey and the Palace of Westminster.
