Romanesque vs. Gothic Architecture

In Spain, many Romanesque churches, monasteries, and cathedrals were built between the 11th century and the mid-12th century.

Here are some of the characteristics:

--Stone replaces wood as the main construction material.

--Buildings had thick walls and not many windows. The windows were small.

--The arches were semicircular.
--They used barrel vaults.

Here is a Romanesque church, San Martin de Tours, in Palencia.

Gothic Architecture was popular from the 12th century to the 16th century.  

Its characteristics:

--Churches were tall and let in a lot of light.

--Walls were thinner and had large, stained-glass windows.

--The pointed arch was used.
--They used ribbed vaults.

Can you find all three of these characteristics in the Cathedral of León?
