How are the roman arches so strong?

The Roman Empire became strong through its policy of divide and conquer. It would keep its enemies from cooperating. Then it would attack its enemies one at a time. When it was finally able to break...

Best weapons -------------------------------- Also the high discipline the the roman legions were very famous for, and the extensive training a legionnaire had to go through before joining the ranks...

It's strong because of all the bricks. The bricks are special bricks called "Madikers". These madikers have a big ball of fire in them. You put the madikers quickly on one another to keep them strong.

Of course. The arch is perhaps the strongest support structure that you can make with rocks or bricks.

Because they are made of strong wood!!!They are glazed with a fine paste.
