The Spanish monarchy doesn't quite boast the worldwide clout of the British monarchy, but royalty is royalty, right? Take the chance to step into sovereignty when you enter the Real Alcázar palace and gardens. The palace was built in the seventh century and it still occasionally hosts the royal family when they visit Seville. While the original structure dates back to the Middle Ages, the entire palace has been heavily influenced by different architectural and cultural styles, ranging from Gothic to Baroque. The intricate architectural design is known as mudéjar — a Muslim and Christian artistic fusion unique to Andalusia. Exlpore on your own or use an audio tour to guide you through the luxurious rooms of the palace like the Salón de Embajadores (Hall of Ambassadors) and the Patio de las Doncellas (Patio of the Maidens). But to gain access to the Cuarto Real Alto (the Upper Royal Quarters), you'll need to be on a guided tour.

Make sure to budget enough time to admire the details. One TripAdvisor reviewer suggests: "Be sure to look upwards when you walk through this grand residence of kings, because the workmanship of the carvings and painting on the ceilings is truly amazing." This UNESCO World Heritage site is surrounded by gardens that are also worth seeing.
