Historic wonders await in the Rotunda Museum!
Suspended from the ceiling of its dome is the Saturn Lamp, a stained-glass light fixture crafted by the Los Angeles Light Company in 1918. Other noteworthy items on display in this venerable building are Percival Lowell’s first telescope, the blink comparator Clyde Tombaugh used to discover Pluto (recently returned from the Smithsonian!), and an interactive OmniGlobe.
