well, it wasn't me who constructed it, i only gave the idea, anyway, there wasn't much construction, he only built up one more layer of bricks. all material is OLD, from a castle ruin, the main two rocks were brought here mroe than half a century ago, while the bricks were "looted" now, but we didn't ruin anything, only picked them up. some really FINE bricks were made 200+ years ago. you don't see that kind nowadays
