Keystone Gates

One of the famous landmarks of Keystone City.

About
Due to Keystone City's size and labyrinthine city plan, smuggling, trade, traffic and so much more need to be controlled, or at least monitored. These gates provide at least the appearance of these measures. The Cornerstone is expected to build them as a display of economic prosperity.

They vary between ornate to slabs of stone cleverly attached to rocks.
