A striking Neoclassical building midway along Edinburgh’s Princess Street, the National Gallery defies you to miss it. Widely regarded as one of the finest smaller galleries in the world, this collection is a manageable concentration of excellence. Housed here are works by the greatest names in Western art – Raphael, Titian, El Greco, Rembrandt, Rubens and Monet, to name but a few – as well as the most comprehensive array of Scottish masterpieces. While some galleries tend to intimidate, this one is refreshingly intimate.
