Meneltarma, meaning Pillar of the Heavens, was a sacred mountain in the centre of Númenor.
It had a flattened and broad summit, able to contain a great multitude during religious ceremonies. However no permament structure was erected there, and the ceremonies took place in open air.
A requirement of absolute silence was imposed on any who climbed the mountain. The tradition was so strong and universal that even foreigners felt bound by it. Only the King was allowed to utter prayers and thanksgivings to Eru Ilúvatar, during the feasts of Erukyermë, Erulaitalë and Eruhantalë.
Birds and animals did not approach the site, and only the Eagles of Manwë were seen circling over the summit. They were also regarded as sacred guardians of the mountain and all the land.
The base of Meneltarma sloped gently and divided itself into five roots reaching out towards the five divisions of the land. These roots were called Tarmasundar, the Roots of the Pillar. On the southern slopes were located the tombs of Kings and Queens of Númenor, in a valley called Noirinan.
After the destruction of Númenor, the only trace of the island was a very small island , and it on it was what was left of the great mountain.
