sevilla part two
On our second day in Seville we first passed by the Seville Cathedral, the largest Gothic cathedral (and cathedral, period) in the world. We then visited the Metropol Parasol, an immense wooden structure by Berlin architect Jürgen Mayer H. The building mushrooms over a large public plaza with an indoor market below. We took an elevator (not free) up to the roof which contained a restaurant, event space, and walkways that snaked over the roof surface offering incredible views of Seville and beyond.
On our drive back to Portugal, we spotted some strange towers on the horizon and decided to investigate. They turned out to be the solar power towers of Abengoa Solar's Solucar Complex, a series of solar power generation plants. The towers are surrounded by thousands of heliostats (sun-tracking mirrors) that direct the sun's rays to the top of the towers to superheat compressed water. The water is converted to steam, driving a turbine and generating electricity.
