The Altazimuth Pavilion was built in 1899. It was originally intended to house instruments used to measure the two coordinates used to fix the position of a celestial body in the sky: the altitude (its position above the horizon) and the azimuth (its position east along the horizon), and it is from this coordinate system that it gets its name.
The ground floor of the building contains a small exhibition on the Sun, which is open daily. The upper floor under the dome contains two historic instruments used by the Solar Department at the Royal Observatory until 1949, and is only accessible for special talks and observing events on specific dates throughout the year. The instruments currently housed in the dome include the Newbegin 6.25-inch Refractor and the historic Dallmeyer No.2 Photoheliograph.
