Zaltbommel

I'll come back to the abseilers later.

We went for a wander around the town and neighbouring countryside.  It's not until you look at a plan view of the town that you realise quite how much of a fortified settlement it was.  

It has a major canal / river to the north - which still carries a lot of cargo in outstandingly long (how on Earth do you steer that thing?) barges.  I'd guess it was a strategic crossing point (now a motorway and railway bridge pair).

To the south there's a network of double moats (I guess that's the handy structure in a flat, wet country) and an inner wall.

The town itself is delightful and of a size that's easy to walk around the whole old town in not very long at all.  There's a nominal 'castle' - rather more small stately home with lots of turrets, that's now a museum.

While wandering, we came across these two abseiling down the main church in the town.  Turns out it was a rehearsal for a performance art piece later that afternoon, featuring these two, plus a couple of parkour runners.  Intrigued, and with the family artist present, we booked.

By the time of the performance it was drizzly so I didn't get the proper camera out then, then it moved inside with lots of running around, organ music, and stuff.  Not entirely sure I understood what it was all about but it entertained us in the dry for a while.
