Cathedral

The Cathedral is the most expensive room in the game, and is the last requirement to reach Tower status. It costs 3,000,000 to build and can only be built at level 100. When a sim gets married in the Cathedral with 15,000 sims in the tower, the player earns the Tower status. This room is unlocked when a tower reaches a 5-Star Rating. Despite being used by sims, it does not increase the tower's population.
