The city council has realised that the pedestrian areas of Bordeaux are short of shade, especially in terms of tree cover. Pedestrianisation has been pretty rapid and extensive. It's great. It means that huge areas of the city are easily accessible and safe on foot. But there are HUGE squares with no shade at all and many of our lovely streets also have no trees.
So the city council has decided to plant 20,000 trees over the next three years and they've made an immediate start by putting tubs of trees in the square outside the town hall.
