Dalongdong , or Toalongpong (; and variants 大浪泵/大隆同), is an old village in historical Taipei located nears the narrows of the intersection between the Keelung and Tamsui Rivers. The district has since been merged with the newer Twatutia district in the south during the Qing dynasty to form Datong District.
The village officially created in 1853 (3rd year of the Xianfeng Emperor) covers the area extending from the Chen Teacher's abode and beyond the area of sishisikan and the Taipei Confucius Temple. During Japanese rule of Taiwan, the villages of Twatutia, Toalongpong, and Bangka were combined with the walled-city of Taipei (in present-day Zhongzheng District) and incorporated into present-day Taipei city. Although this district now exists only historically, its name still officially remains in the Dalongdong Baoan Temple and on bus numbers 303 and 669 of the Taipei bus system.
