Sunny afternoon on the Ertholmene. View from Frederiksø across the natural harbor towards Christiansø. Slightly left from the center you can see the pedestrian bridge which connects both islands. The bridge is actually constructed as a double swing bridge so it can be „split“ in the middle and both parts swing to the side to let bigger vessels pass through. The round tower in the center is called "Store Tårn" (=Big Tower) and contains the lighthouse.
