Ometepe is an island formed by two volcanoes rising from Lake Nicaragua in the Republic of Nicaragua. Its name derives from the Nahuatl words ome (two) and tepetl (mountain), meaning two mountains.
The island first became inhabited in the Dinarte phase (ca 2000-500 BC), although evidence is sketchy. The first known inhabitants were Nahua Indians from Mexico. In their footsteps came the Niquirano Indians, who established an important settlement on the island. Their ceramics and monuments still amaze./Wikipedia/
