The telescopes on the wall of the building represent two of the Greenwich instruments. The one on the right is the Troughton 10-foot Transit Instrument, which defined the Greenwich Meridian from 1816–50. The one on the left is Hooke’s 10-foot Mural Quadrant. Made in 1676, it failed to work properly and was soon abandoned by Flamsteed for whom it was made.
