Bartender at The Three Broomsticks
- "Naturally. Never saw one without the other, did you? The number of times I had them in here — ooh, they used to make me laugh. Quite the double act, Sirius Black and James Potter!"
- —Rosmerta mentions that she was a barmaid [src]
Rosmerta was older than the Marauders, as she was the barmaid whilst they were all still at school. Rosmerta lived in and was the barmaid of the Three Broomsticks during the First Wizarding War; she was a listener of gossip and believed the rumours that Sirius Black had turned his friends, the Potter family, over to Lord Voldemort to be true when news broke out they had been murdered and that the war was over. It remains unknown how she reacted when the true story was told to her, (that it was Peter Pettigrew who betrayed the Potters) or, indeed, if she ever found out.
She continued to tend bar during the 1980s.
Rosmerta was interrogated by Patricia Rakepick regarding the possible whereabouts of Jacob's notebook and map. She claimed to know nothing and threatened to inform some of her best customers from the Department of Magical Law Enforcement regarding Rakepick's behaviour.
In 1993, Madam Rosmerta was angered when Dementors were in Hogsmeade to catch Sirius Black because their presence was scaring away many of her customers. She hosted an informal meeting between Minerva McGonagall, Cornelius Fudge, Filius Flitwick, and Rubeus Hagrid discussing Sirius Black and his friends. They discussed how Sirius Black had been named Harry Potter's godfather before the Potters' demise.
In 1997, it emerged that Rosmerta had become an unwilling agent of the Death Eaters. In order to fulfil his mission to assassinate Albus Dumbledore, Draco Malfoy had managed to place Rosmerta under the Imperius Curse. He used her to pass on a cursed Opal Necklace to Hogwarts student Katie Bell, who accidentally touched the necklace and was subjected to the very harmful curse intended for the Headmaster. Rosmerta also poisoned mead that was intended to be given to Dumbledore through Horace Slughorn in the guise as a Christmas present, but it was unintentionally drunk by Ron Weasley, who was saved by Harry Potter; Harry had shoved a Bezoar down Ron's throat to save his life. Malfoy communicated with Rosmerta through fake galleons, copying the idea from 'the Mudblood Granger' and Dumbledore's Army.
After Harry and Dumbledore had been to the cave to retrieve a locket they believed to be one of Voldemort's Horcruxes, they apparated to Hogsmeade, where Madam Rosmerta alerted them to the presence of the Dark Mark above the school and gave them brooms on which they could travel rapidly back to Hogwarts, where Draco's plan could be brought to completion. Harry Potter eventually cleared her name as he felt that that investigation on Albus Dumbledore's death may link to her.
Rosmerta is an attractive woman, described as "a curvy sort of woman with a pretty face". On one occasion, she was seen wearing glittery open-toed high-heels. Several Hogwarts pupils, including Ron Weasley, have fancied her.
Rosmerta was the Romano-Celtic goddess of fertility and abundance, known as the "Great Provider". In Latin, it means "good purveyor" or "great provider".
Behind the scenes
- Madam Rosmerta was portrayed by British actress Julie Christie in the film adaptation of Harry Potter and the Prisoner of Azkaban. She only appears twice in the film; once at the Three Broomsticks and again, on close observation, when Harry and Hermione go back in time. Her role was reduced to this film alone as she did not appear in any of the subsequent film adaptations of the novels.
