Newroad gate Kathmandu

When I was child, I used to look at the 'New road gate' of Kathmandu turning my head several times. The reason for that was the four heads which were holding the structure. Now a days, I hardly look for that reason but I look for its history and craft. Today, when I saw it, I feel that the concern authority is not caring it much. The traffic has increased, population has increased who pass the gate but either coloring nor removal of herbs from the gate is clear indication of careless. See the condition yourself.
