In Baarle there's a special point, a so-called quadripoint. The Belgian enclaves H1 and H2 in Baarle meet each other at 1 point.
In February 2003 we visited this spot and it was well recognizable in the landscape. De Belgian fields had another type of crops. On the apparent quadripoint-spot there was a metal pipe stuck in the ground which we assumed to be a kind of bordermarker. There were no others in the vicinity and it was definitely no drainage pipe or like. If this is the REAL quadripoint, only a land-surveyor can tell.
