These shrines serve as places of worship, pilgrimage, and reflection, attracting millions of devotees each year. Notable examples include the Imam Ali Shrine in Najaf, Iraq, and the Imam Hussein Shrine in Karbala. These sites are not only religious centers but also cultural landmarks, showcasing intricate architecture and art that reflect the rich heritage of Shia Islam.
