Start the Pavilion

Completion
The Pavilion requires a large clear area, and when first placed from your Inventory, looks like a square of dirt surrounded by black and yellow tape.

The second part of the quest requires that you click on the square of dirt to begin hammering. This will cost 75,000 Silver Coins and take 12 seconds.

The third part of the quest requires that you click the square of dirt again. Hammering requires 30 Stone Blocks, and takes 30 minutes.
