Fantastic observatory. Beautiful architecture and historical significance. Amazing tour guide and very accommodating to families. Even if you can't get a ticket, the outdoors area is always accessible and beautiful to walk around.

You have to buy tour if you want to enter the observatory. Could not find parking spot other than for the tour.

Several wonderful paid tours here, all about the history & the famous astrophysicists who spent time here. Highly recommended.

Did their Luminary night walk. It was magical! What a beautifully restored historical gem! Staff and volunteers were amazing and all seemed excited to be there. The bus service to the event was convenient and efficient! We love coming to their events!!
