3 Best Day Trips from Madrid: Segovia, Toledo, and San Lorenzo de El Escorial | Condé Nast Traveler
"Architecture buffs will love the Toledo Cathedral, a quintessential example of Spanish Gothic style. This historic cathedral, built on the site of a former mosque, was born under the auspices of Ferdinand III, but the structure took centuries to complete and many of the chapels and naves were added by subsequent rulers. Still used for regular services, the church has a small entrance fee for non-worshippers. If you're short on time, don’t miss El Greco’s portraits of the 12 apostles, housed in the museum." - Ramsey Qubein
