Port
From Project Rebearth
The Port is a major infrastructure building that enables maritime trade with other settlements. It is the primary structure for establishing sea-based commerce and serves as the anchor for all port-related construction.
Overview
The Port must be placed on a coastline and requires 20 workers to operate. It is one of the most resource-intensive buildings in the game, costing 1,000 of the local biome resource, 500 of a secondary material, and 50 
Tools in every biome. In the Wood and Arctic biomes, construction requires 1,000 
Wood and 500 
Stone. In the Stone biome, construction requires 500 Wood and 1,000 Stone. The Earth biome substitutes 
Earth for Stone, requiring 500 Wood and 1,000 Earth.
Once built, the Port unlocks trading, halves all transport costs, and provides 5,000 units of trade storage capacity, making it a critical investment for settlements that rely on importing or exporting goods. By comparison, the Market offers only 1,000 units of trade storage.
The Port also acts as a parent structure for further maritime expansion. Docks can be constructed within 20 meters of the Port, and ships (Small Ship, Medium Ship, and Large Ship) can be built from Docks to increase trade volume and range.
