If you plan on exploring the place fully, be sure to bring a flashlight because even during the day, the basement is extremely dark and there are many holes in the floor.
the place is still standing when I went a couple of weeks ago. pretty easy to get in from the riverside. as long as you keep quiet while you're there you shouldn't have a problem.
They definitely increased security on this place so be careful. Was much more difficult than it has been in the past but absolutely beautiful site!
Still a lot left to explore here.
such a shame to loose a great piece of history
