Could have been interesting. I expected a lot more for a $10 admission. The 'history' consisted of an explanation of the carvings around the foyer and the pillars through an exterior door and a 5 minute view of ( not through) the 42 ft (?) telescope. I hardly call standing in the initial foyer and up some stairs to see a huge telescope, a tour.

The tour guide was very knowledgeable but the tour seemed slow and there wasn't as much to see as we anticipated.

You might consider telling people that there a lot of stairs. I thought there would be a lot of walking, which I can handle. All the stairs were difficult for me. Otherwise, the tour and tour guide were wonderful!

it say a tour but we stood for 45 minutes in the hallway while a man show picture of other men an talked about lens that was way over my head. by the looks of other elder people they rolled their eyes also. we did see the telescope for 10 minutes and that was it. you did not see the inside of the building which was building in the 1890 but you saw none of it. very disappointing. I would not go back and maybe provide seating for the elders. even I was tired of standing for 45 minutes. the tour guide even mix up the pictures and names of the builder. this tour needs help.

The observatory is awesome in every respect. The guide was well informed and pointed out some little known facts. Plan to return during the evening when they have viewings thru the telescope.

Our guide, Richard, was very knowledgeable. The history of the telescope and the architecture is very interesting.
