Plaza
From Project Rebearth
The Plaza is a decorative town building placed by drawing a polygon area on the map. It paves the ground with stone tiles, providing an aesthetic foundation for town centers, marketplaces, and public spaces.
Overview
The Plaza is a polygon-type building, meaning it is placed by drawing an area rather than placing a single point. Its cost scales with size at 0.1 
Stone per m², making a 100 m² plaza cost 10 Stone and a 1,000 m² plaza cost 100 Stone. This cost is the same across all biomes.
The Plaza has no production, no population requirements, and no upkeep. It serves a purely aesthetic and organizational role, allowing players to define paved areas within their settlements. It pairs well with other town buildings such as the Market, Town Hall, and Tavern to create a distinct town center.
