Seville: Once the largest cathedral in the world, the Catedral de Santa Maria de las Sede incorporates a minaret built in 1184. The famous Feria de abril de Sevilla, the Royal Palace and its sumptuous gardens. Then to Cordoba once the greatest and most sophisticated city in the world and from where the Renaissance sprang. The astonishing El Mezquita; half mosque and half cathedral. The Patio Garden Competition shows what can be done in a tiny space. The formal gardens of the Alcazar de los Reyes Cristianos show what can be done in a vast space.
