At the confluence of two rivers sits this impressive royal palace, one of the residences of the King of Spain. The palace was constructed by three monarchs, each adding their particular touches which lend the palace its unique style. It is also home to important art and history collections which tell the story of the lives of Spanish monarchy. The Porcelain Room and Mirror Room are particularly spectacular, as is the palace's majestic staircase. Step outside and admire the gardens, adorned with fountains and bursting with vibrant colors.
