Baghdad, the historic capital of the Abbasid Caliphate, stands as one of Islam's most significant cities and former center of the Islamic Golden Age. The city houses magnificent Islamic architecture including the Al-Kadhimiya Mosque with its golden domes, the Abu Hanifa Mosque, and remnants of the ancient Round City built by Caliph Al-Mansur. As the birthplace of the House of Wisdom and home to millions of Muslims, Baghdad continues to be a vital center of Islamic scholarship, Shia pilgrimage, and rich cultural heritage despite centuries of challenges.
