Puerta de la Tierra

The Puerta de la Tierra (literally, Door to the Land, Landing Gate maybe, or even Gate to the Earth, because Spanish only has one word, puerta, to serve for both door and gate and only one, tierra, to signify land or earth - as in dirt or planet) in Garachico, is set in a lovely tree-filled garden behind the Plaza de Juan Gonzalez de la Torre. This "stone structure was designed to control passengers and goods that came in and out of the port. It dates back to the very origins of the Port of Garachico itself.", say PuntoInfo. Since the 1706 eruption that filled in Garachico's deep water port, the Puerta de la Tierra has been quite a long way inland.

This full size image shows the two major lava flows that affected the town. The bright green one, at 9 p.m. on May 5th, 1706 was the one which filled in the port. You can see from the dotted blue line shown on this image of a modern aerial photo, overlaid with the paths of the 1706 lava flows, where the limits of the former deep water port had been. Just to the left edge of that blue dotted line is a square dark green patch. That is the Parque Puerta de la Tierra, where this structure is located. See where this picture was taken. [?]
