The Cathedral of San Cristóbal de La Laguna is a gigantic church consecrated when La Laguna was the capital of Tenerife. The walls that support it recount different episodes in the island's history; in fact, through it you can trace a chronological map of the city's architecture, leading up to the present century. Its history began in the 16th century and continues through neo-Gothic and neoclassical renovations. One of its unique features is that it is the only cathedral with concrete walls. The latest renovation was completed in 2013, using cutting-edge construction materials and techniques. It's one of just two cathedrals in the Canary Islands (the other being Gran Canaria's Cathedral of Santa Ana).
