Solid memory

Last day in Prague and the sun is shining! Been walking past this monument every day between the office and the hotel with out a clue who it is about. It's a properly solid lump of granite with the holes drilled right the way through and much easier to read in the photo than in real life. A quick bit of googling tells me he was an artist, writer and poet who died in 1945 in a concentration camp. More details here
