We found 2 options to enter, 1 was within sight of a walking path over a 2.5-meter high ornamental fencing with spear points and the 2nd option was out of sight through a small toilet window.
So it became the 2nd option which was quite a task. Don’t ask me about the way back where I almost got stuck due to a wrong approach.
But once inside it was well worth it. Beautiful rooms, a huge hall with an old sofa, a grand staircase, and even a beautiful chapel
