Today I got out of the flat for some exercise by walking into and around the centre of Brussels and back again – some 12 km! The more touristy areas would normally be very busy. In the usual run of things, Grand Place would have hundreds of tourists milling around examining the medieval architecture of the square.

I had an eerie experience walking down the steps onto Mont des Arts, which was almost completely deserted and was so quiet I could hear my own footsteps.
