Architecturally one of the great British railway stations. John Dobson's curving 200-metre train shed of 1850 was the first to use a curved roof structure of any size, and Thomas Prosser's portico and porte-cochère at the front provided the prototype for similar treatments at York and Manchester.
Worth a few minutes' look even if you are not catching a train. The original wrought-iron station name above the entrance is still in place; the interior shed roof, with three parallel arched spans of glass and iron, is best appreciated from the platforms.
