Mount Othrys ( – oros Othrys, also Όθρη – Othri) is a mountain range of central Greece, in the northeastern part of Phthiotis and southern part of Magnesia. Its highest summit, Gerakovouni, situated on the border of Phthiotis and Magnesia, is above sea level.

On February 5, 1991, a Lockheed C-130H Hercules 748 crashed into the mountain, killing 63 people.

Greco-Roman Mythology

In Greek mythology, Mount Othrys was the base of Cronus and Rhea and the other Titans and Titanesses during the ten-year war with the Olympians known as the Titanomachy. It was also the birthplace of the gods and goddesses who are children of Cronus and Rhea: Hestia, Demeter, Hera, Hades, Poseidon, Zeus. It was assaulted by the Olympians against the Othrysians, led by Cronus and Rhea's six sons and daughters. The Olympians later overthrew and restored the Othrysians and both gained dominion in all of heaven and earth.

Tunnel

Othrys Tunnel () is a tunnel long located in the southern section of the A3 (Central Greece) motorway, between Lamia and Xyniada. It passes underneath Othrys mountain. Work began in 2008, along with the rest of the motorway, but stopped in 2011 because of the Greek government-debt crisis. Construction resumed in 2019, along with the rest of the southern section. Its construction has faced challenges. It is the longest road tunnel of the A3, and it will be one of the longest in Greece. The tunnel has already been excavated on both sides, as of October 2021.
