The fact that a hotel is one of the main sights of a city is an exception.
Until the 1970s, this building on the Wilhelminapier was the head office of the Holland America Line in Rotterdam.
Tens of thousands emigrated from here to America by ship.
Much of the historic flair and original architecture has been preserved. It is the perfect starting point for a city tour.

During our Delft and the Hague tour this would be a prefect place for a cup of coffee.
