Guess, is to ask what is more distinctive, or famous buildings? Let me try to list one or two here:
1) The landmark building of Lanzhou-Zhongshan Bridge.
Commonly known as "Zhongshan Railway Bridge" and "Yellow River Railway Bridge", it is located on the north side of the middle section of Binhe Road, at the foot of Baita Mountain and in front of Jincheng City. Built in 1907 (thirty-three years of Guangxu in Qing dynasty), it is the oldest ancient bridge in Lanzhou and the first bridge on the Yellow River with a total length of 5,464 kilometers, so it is called "the first bridge on the Yellow River in the world".
Other characteristic buildings:
2) Jin Chengguan Ancient Architecture Complex-Jin Chengguan.
3) Baita Mountain in Yuan Dynasty-Baita.
4) Wuquanshan architectural complex
5) The mother of the Yellow River-sculpture.
6) Lanzhou Waterwheel Expo Park-Waterwheel.
7) Lanzhou forest of steles
8) Lanzhou Hotel (old building, ready to be demolished and rebuilt).
9) Lanzhou Theatre (old building, ready to be demolished and rebuilt).
