The valley square is said to be the largest in Europe (I doubt it, I say), and the central fountain is crystal-like with street lights. What attracted me most was the trees in the square, dressed in colorful sweaters like new clothes for the New Year for children. The guide looked at the sign on the tree and told us that every tree in a sweater here represents a dead child, and these trees are dressed in clothes to commemorate the children in heaven. Ah, so it turned out, give them a hug, and hope that you will be happy in heaven.
