On Dragør Harbour is this funny little house. It's called a pitch house or cooking house and it was used to boil tar and pitch for the boats and to cook meals for visiting sailors. The house is from 1770 and it replaced an older one that was torn down when the harbour was expanded. This house was a necessity in an age where open fire on board the boats was strictly prohibited when moored due to the risk of fire; open fire and wooden boats covered with tar, hemp ropes and cotton sails make for a bad combination. These houses were found in all harbours but only three remains in Denmark, one each in Dragør, Assens and Ærøskøbing.
