Astronomical Observatory

Here in volcano in 1860, miner and amateur astronomer George Madeira built California's first astronomical observatory of record and operated it for two years. Using a three inch refractor telescope he studied sun and moon, stars and planets, and other glories of the heavens, including the great comet of 1861.

California registered historical landmark no. 715.
