Absolutely the top sight in Toledo with its mix of Gothic, Renaissance & Baroque styles and a unique transept that has a hole cut into the ceiling to let light in, it's breathtaking.
I am totally blown away by the fact that 3 religions of architecture styles were built together. Must visit, must with a tour guide who knows the history.
Historical Cathedral of Toledo, it survived the Arab dominance over the Iberian Peninsula, turning from a Catholic Church to a Mosque and again to a Catholic Church.
