Belgrade has several boulevards and streets lined with plane trees (platanus), which are very similar to those known in the US as sycamores. They grow to great heights, and in cities their extensive branches often interfere with phone, power, or trolley lines. Hence the reason why Belgrade amputates its trees every spring...believe it or not, these trees will be quite full by summer's end, and a lovely autumn photo will be waiting! (I don't see any such lines near the trees on the right---maybe the goal is symmetry on this heavily traveled boulevard.)
