Isabela Island is the largest of the Galapagos Islands with a total land area of 4640 km2 (1790 ml2) and length of 100 km (62 miles) almost 4 times larger than Santa Cruz, the 2nd largest of the archipelago. The island was named after Queen Isabella of Spain, but originally it was named after the Duke of Albemarle. Isabela Island strides the equator.

One of the youngest, Isabela Island is situated on the western edɡe of Galapagos archipelago close to the Galapagos hotspot. At nearly 1 million years old, the isle was formed by the merger of six shield volcanoes. The settlements of Santo Tomas and Puerto Villamil were founded in 1893. By 1905, island’s inhabitants were 200. Exports at the time were lime made from coral and sulfur mined from fumaroles. Tortoises were used for oil and meаt. Popular attractions include the Flamingo Lagoon and El Muro de las Lagrimas wall (built by prisoners at the time when the island was a penal colony). Both are located in the south of Isabela Island.
