Giải cho mình exercise 1 và exercise 2 nhe ----- Nội dung ảnh ----- Hadrian's Wall
Hadrian's Wall is a UNESCO World Heritage Site in the north of England.
Hadrian's Wall is open 365 days a year and the best way to see it is on foot between May and October.
Visitors can walk along the Hadrian's Wall Path beside the wall. But standing on the wall isn't a good idea because it is dangerous and it damages the stones.
The wall is 117.5km long and the stones in it are very old.
