A fortress visited by the warrior maiden Britomart. There, she found the Red Cross Knight attacked by six knights. She assisted him, and the two of them defeated the attackers.
The lady of the castle, Malecasta, had wanted the Red Cross Knight as her lover. When the Red Cross Knight and Britomart lodged at the castle, Malecasta turned her affections to Britomart, not realizing that Britomart was a woman. This misunderstanding led to another brawl, and Britomart and the Red Cross Knight had to flee the castle.
