The main island is clearly a place where tourists visit, there being many shops and restaurants along the small streets. Helgoland is a tax-free zone, so items that are usually taxed heavily, like alcohol, are a lot cheaper. Helgolanders are obviously very proud of their gardens!
The architecture is modern because the island was virtually destroyed in WWII. The island is very well-known to birders for being a hotspot for rarities. As birds migrate north for the summer and south for the winter, many take a rest on Helgoland, and some take refuge there if they are blown off course.
While we were there, a species of warbler from Siberia was seen. During our hike over the top of the island, we saw many Northern Wheatears, which were clearly on migration south.
Around lunchtime we all came back to the Fram and continued our voyage, this time to Amsterdam, where we will be tomorrow. Along the way we sailed by several marine windfarms supplying power to Germany.
And on the way we picked up some stowaways in the form of about a dozen Barn Swallows. They will likely hitch a free ride all the way to Amsterdam!
