A small building built in the sixties of the nineteenth century in the heart of the port. It is very small and has an area exactly 3 * 3. It was used by fishermen and workers in the sea to boil the tar and make the sails waterproof before starting their journeys across the sea. Because the tar was easily ignited, this building was built a good distance from the other harbor buildings. Thousands of visitors visit this small building, which still stands today, to learn about the city's history.
