The Great Wall of Parak Tingga is a janjang that connects Jorong Lambah with Jorong Sianok Nagari Sianok Anam Suku. In the past, this janjang was a shortcut for people in Jorong Sianok who would go to Jorong Lambah, especially school children in Jorong Sianok who would go to SMP N 2 IV Koto located in Jorong Lambah. Initially, this janjang was only a dirt road, but over time, to facilitate road access for the community, a janjang (ladder) resembling a great wall was made. The location of the Great Wall of Parak Tingga is indeed somewhat covered by shady trees. Precisely the location of the Great Wall of Parak Tingga is in the middle of the road to Jorong Lambah. There will be seen the gate that reads Great Wall of Janjang Parak Tingga.
