Double Aisles for Kids - what is a double aisle? Why did some churches have double aisles?

Double Aisles

Aisle - Pisa Duomo
Looking into the side aisles of the Pisa Duomo (Italy, 1064 AD)

Some big basilicas and churches had two aisles instead of one. The big cathedral at Pisa (the Duomo), has two aisles. See the two rows of columns?

Very big churches needed double aisles. The extra row of columns helped to hold up the heavy stone roof.

Here is a floor plan of Pisa Cathedral, looking down at the church as if you were floating over it. You can see the four rows of columns, and the side aisles, and the apse at the other end.
