Shinagawa Battery Islands
The Tokugawa Government commissioned Egawa Hidetatsu in 1853 to build several fortresses in Tokyo Bay to protect Edo from foreign ships, namely Commodore Perry, who also arrived that same year. Egawa's plan originally consisted of 11 man-made islands and three additional batteries placed around the mouth of the Sumida River. In just over a year, 6 of the original plan were completed, but due to a lack of funds and emphasis being placed on other fortifications, such as Goryokaku, the remainder of the plan was abandoned. Since WWII, most of these islands were destroyed or absorbed by fill-in projects such as the Tennoz Isle area. Only islands #3 and #6 remain today. Island #3 is now connected to the Odaiba Kaihin park by a landbridge. You can get a good view of each island by walking across the Rainbow Bridge.
Walk across the Rainbow Bridge to get the best views. After visiting here you could also take a river boat bus from the landing next to the Odaiba Kaihin Park up to Asakusa. I'm not sure if this is a separate castle or an extension of Edo Castle, but most of my materials list it separately, so I will too.
