George Scharf’s 1832 watercolor depicts the interior of the main hall in the National Gallery of Practical Science, Adelaide Street, on the north side of the Lowther Arcade, West Strand, London.

This watercolor captures a view of the British Museum’s Egyptian Room, and a portion of the Townley Gallery beyond, as they appeared in 1820. Visible in the Egyptian Room are a series of monumental stone sculptures, placed on low plinths, that run along either side of the central walkway.

This image depicts the interior of Thomas Gwennap’s “Oplotheca” (derived from the Greek term hoplothêkê, meaning armory) at no. 20, Lower Brook St., London, as it was arranged in 1816. On the left side of the image, along the wall, stand three full suits of armor, flanked by two armored equestrians.

Joseph Gandy’s watercolor depicts what would become the “Dome Area” of John Soane’s house in Lincoln’s Inn Fields, London. The image illustrates how Soane, a prominent architect and collector, conceived of the space while it was still in the planning stages: the watercolor was produced in 1811, a year before the Dome Area’s construction.

This hand-colored engraving, produced by Rudolph Ackermann in 1810, depicts the second floor of William Bullock’s Museum at 22 Piccadilly, London.
