Theodor Jacobsen Observatory

The Theodor Jacobsen Observatory is the on-campus observatory of the University of Washington. Built in 1895, it is the second oldest building on campus and was constructed using the remaining Tenino sandstone blocks from Denny Hall, the oldest and first building on campus. The refracting telescope, enclosed within the dome, has a 6-inch Brashear objective lens on a Warner & Swasey equatorial mount. The observatory also includes a transit room on the west side and a 45-seat classroom, which was built later, on the south side.
