侵华日军第七三一部队罪证陈列馆 Qīnhuá Rìjūn Dì Qī Sān Yāo Bùduì Zuìzhèng Chénlièguǎn
A museum at the site of a former bio-chemical weapons research and testing facility built by the Japanese army during World War II and used to perform experiments on over 10,000 civilians and POWs. The museum tells the story of these individuals. The displays are very extensive with detailed information in both Chinese and English, though you may struggle to see everything due to the very large number of people that typically visit the museum. After looking around the museum, you may then visit the actual buildings where Unit 731 carried out its notorious research, including the main administration building and the burnt-out remains of the prison facilities.
龙塔 Lóngtǎ
Tallest steel structure in northeastern Asia. Only built for the Chinese need of having something as the biggest and the best. Somewhere along the way they forgot to add any pleasant looking qualities to it. There is a revolving restaurant on top and views of the city. You can walk outside at the top and even strap on a harness for a thrill.
