Places in Middle-earth
Dome of Stars
'The chief and master of these [Stones] was under the Dome of Stars at Osgiliath before its ruin.'
The Two Towers, LoTR Book 3, Ch 11, The Palantír
In that siege and burning the Tower of the Dome of Osgiliath was destroyed, and the palantír was lost in the waters.
The Return of the King, LoTR Appendix A, Annals of the Kings and Rulers: Gondor and the Heirs of Anárion
The palantíri were no doubt never matters of... common knowledge.... In Middle-earth they were kept in guarded rooms, high in strong towers, only kings and rulers, and their appointed wardens, had access to them, and they were never consulted, nor exhibited, publicly.
Unfinished Tales, Part 4, Ch 3, The Palantíri
