We drove out to the Delaware shore this weekend with the hopes of defying the weather and spending some time on the beach. It ended up staying rainy and windy but we still had a lot of fun exploring the beaches. These big towers are part of the WWII Coastal Defense System that guarded against potential U-boat attacks.
I know, I was thinking the same thing, "Why would the German's bother attacking Delaware?" I guess this was the main entry to Philadelphia's ship building industry. Guarding the boardwalk at Rehoboth from the Luftwaffe was more of a secondary objective.
Anyway, the towers were pretty cool and reminded me of the coastal defense against the Japanese out in California.
