The Octagon House is an interesting bit of Watertown history. I don't normally visit these kinds of attractions, but I was curious. The price for a guided tour of the house is $10 per person. The tours start at the top of the hour between 12 and 3. The woman leading the tour was friendly and happy to answer any questions we had. Besides my wife and I, there were three other people on my tour. The rooms are somewhat small, so I am glad we didn't have a larger group. Otherwise it may have been difficult to see the details. The house is nicely furnished in what I assume is period appropriate. I enjoyed the tour and appreciated the ability to ask questions. Unfortunately, one hour was not sufficient time for me to fully experience the house and all it had on display. I realize that people generally cannot be trusted to behave themselves, but I wish I had more time to experience everything at my own pace. To compare, I spent 1 hour in Octagon House, with 5 floors and many rooms. I spent another 45 minutes on the self guided portion which included an old barn and the country's first kindergarten, which was basically two large rooms. I enjoyed my visit overall, but doubt that I would return unless I could explore at a more leisurely pace.
