Usedom (Polish: Uznam) is an island in the Baltic Sea belonging both to Germany (more significant western part) and Poland (minor eastern part).
Its seaside resorts have been a trendy summer retreat for people from the Baltic Sea region and beyond since the 19th century. Usedom is nicknamed Sunny Island for being the sunniest spot in the Baltic Sea in Germany and Poland.

1️⃣ Peenemünde — site where Wernherr von Braun and his team developed and tested the V1 cruise missiles and V2 rockets, the latter the basis for the Soviet and American space programs. It was destroyed in a bombing raid there is an on site museum there today.
Like in other parts of the Baltic Sea, phosphorus from dumped ammunitions is sometimes washed ashore, especially around Peenemünde with its military past.
Phosphorus is poisonous, ignites spontaneously when dried, and can look deceptively like amber, which leads to occasional accidents. If you collect pieces of amber, don’t keep them in your pocket.
Put them into a vessel that you keep away from your body until you are sure it is amber and not phosphorus. Extinguish burning phosphorus with sand rather than water.
