The grounds of the fort are nice with a museum, excavation site, sitting area with trees and then the fort/tower itself. The walk to the fort is quite a few stairs with no real options up for those who can’t use stairs (to be expected with a ~400 year old structure). Overall it is well kept with a tower at the top that has a great view of Anping (just be prepared for more stairs!). If you’re interested in history I would certainly recommend a visit.
