How many bricks were used to build hadrian's wall?
Hadrian's Wall used 4 million tons of stone. Your exact question can not be answered since the total number of parts that were used are not recorded because it was destroyed multiple times. It was rebuilt every time it was destroyed by Romans. Hope this helps! I made it clearer but the basic information is from: http://www.kgbanswers.co.uk/how-many-bricks-in-hadrians-wall/3677405.
