If I ask which queen died a virgin, I know one. Zhang Yan

She is the sister of Emperor Hui of Han Dynasty, Princess Luyuan, the daughter of Hou Zhang 'ao of Xuanping, the niece of Liu Ying and Hui Di, her uncle. 192 years ago, in order to "get married", Lv Hou made Zhang Qian, who was only ten years old, as the queen, with 12 horse and 20,000 gold as the dowry.

BC 163, she passed away silently at the age of 36. After the death of Queen Zhang, when the ladies-in-waiting washed her body, they were surprised to find that Queen Zhang was as pure as ice and remained a virgin until her death. The news spread like wildfire, and all subjects in the world missed her and sympathized with her. So they built a temple for her, enjoyed sacrifices regularly, respected her as the flower god, and the temple built for her was called the flower temple.
