Panorama Mesdag is a panorama by Hendrik Willem Mesdag. Housed in a purpose-built museum in The Hague, the panorama is a cylindrical painting (also known as a Cyclorama) more than 14 metres high and about 40 metres in diameter (120 metres in circumference). From an observation gallery in the centre of the room the cylindrical perspective creates the illusion that the viewer is on a high sand dune overlooking the sea, beaches and village of Scheveningen in the late 19th century.
