If citizens are particularly conservative, some streets and sidewalks can be protected by the local historical society.
paved are made of high -resistant stones, usually granite or basalt. They were usually dug out of the surrounding areas and then paved or roughly shaped to the required size. The prolonged paving were then set in the sand or mortar. The sand allows the road to gently give traffic and prevent cracking associated with a pavement or asphalt. The streets paved with pavements have shown their durability and longevity by appearing through the wear of part of paved roads around the world. ColorY move from gray to black to purple, depending on the origin of the stone. The patterns in paved streets depend on the creativity of workers who designed the streets and installed paved.
By the end of the 19th century, the paved popularity lost newer techniques in paving on the street.
