"Almudena Cathedral sits adjacent to the Royal Palace, once the home of several reigning monarchs through Alfonso XIII, in the heart of the city center. Both imposing landmarks are free to enter, as are the surrounding gardens, and both are important places to visit for their design and lavish interiors. In addition, the neo-Romanesque crypt and adjacent cemetery of La Almudena hold many notable Spaniards—it's like history come to life. These are must-visit stops for any visitor to Madrid, if only to experience both structures from the outside." - Ramsey Qubein
