The covers in Spain are usually made of metal and are round , square or rectangular
As in other countries, in Spain, round lids placed on a sidewalk are often surrounded by a square frame, which makes it easier to pave around them
On the other hand, there are cases where municipalities still bother to pave in a circular shape around round lids
