Biggest Church Ever

This is the biggest Church I have ever seen. Near where we were, every town was named de la fronteira. This is because when the Spanish were pushing the Moors out, it took a while, so the frontier moved slowly. This building was a church, then a mosque, then a church again. The minaret of the mosque was built on the steeple of the church and the steeple of the new church was built on the minaret of the mosque. The builders of the church aspired to build a church so big that people who saw it were think they were crazy for making it so big.
