For this site, 1 hour..if you do a complete tour of downtown you will need to allot about 3 hours..there is a lot of history to see..I recommend a good tour guide
About 2 hours
If you read everything (like I do), you need at least 4 hours. For an overview, probably 1.5 hours
2 hrs for self directed tour worked for me.
Probably An Hour And A Half Especially On Weekends
I would allow at least 2 hours. There's so much to see and read and interact with, if you do only 1.5 hours, you will miss out (like we did!)
