Out sketching with te Maastricht Urban sketching group again. We were 12, and looked for spot where we could draw together, but with enough distance to avoid Corona problems.
The Fronten are the old fortifications against the French and Spaniards, who wanted to have control over this strategic city. Since the Roman era Maastricht had one of the few safe crossings over the river Maas. This is one of the barracks.
