When they extended the wall behind the houses on Calle Alemania upwards, we did wonder whether they were going to leave it as grey concrete blocks. We also wondered how they might get up there to finish it off. The answers came this morning when a huge crane arrived and parked across from the road below. Its purpose was to carry a cradle holding a man who then had the task of rendering the wall. Hiring such a crane would not have been cheap nor would it be an easy task to position it right. No pasa nada - they just got on with it.
