Recycled Santander's cobblestone

More than 2 years ago, the Plaza Porticada in Santander was restructured, in order to give it a new look, basically something more modern, including the floor. I decided to take a couple of that old cobblestones, completely polished by the cars and pedestrians along decades. Later, I had an idea in order to keep my souvenir alive. I built a wooden box, put the stone inside and filled it with cement. Additionally I decorated it with some small mosaic's tiles, and this is the result: a nightmare for the guys that performed our last moving from Colmenar Viejo to Madrid (only 25Kg, 55lb).
