This beach pavilion opened first in 1889. It's next to the previously described Carmen Sylva (built by the same architect) on the Boulevard Van Schagen.
It was designed by J.J. van Nieukerken and was built for only 33.000 guilders at the time!
It is under restauration now, which is a pity. It currently looks to be a restaurant, so I hope to return some day soon and see.
