Merethrond was the 'Great Hall of Feasts' in the city of Minas Tirith, likely set in the Citadel of the king.

It was there that a huge feast was set upon the arrival of Éomer and his folk to return their fallen king, Théoden to Rohan.

Éomer, when he saw both Galadriel and Arwen, spoke to Gimli of their disagreement concerning the beauty of the Lady of the Golden Wood, and they agreed then to disagree, Gimli giving his love to the morning, while Éomer chose instead the evening.
