Hacı Bayram Mosque (Hacı Bayram Camii) is located in the Ulus district of Ankara, right next to the ancient Temple of Augustus, placing it at the heart of the city’s historical and spiritual centre. Built in the 15th century and dedicated to the Sufi poet and scholar Hacı Bayram-ı Veli, the mosque is an indoor religious site with a modest exterior and a warmly decorated interior featuring wooden details, calligraphy, and a calm, devotional atmosphere. The surrounding square is lively, often filled with locals, pilgrims, and visitors, and the contrast between the mosque and the Roman ruins beside it makes this area especially unique.

Entry to Hacı Bayram Mosque is free of charge, as it is an active place of worship. The mosque is open daily, generally from early morning until late evening, but closes briefly during the five daily prayer times, especially the Friday midday prayer when it can be very crowded. Visitors outside prayer times are welcome to enter quietly and observe. There are no tickets or guided schedules, though the area is commonly included in local walking tours of Ulus. Nearby shops, tea houses, and small religious book and souvenir stalls are open throughout the day.

As a functioning mosque, visitors should follow basic mosque etiquette: modest clothing is required (shoulders and legs covered), shoes must be removed before entering, and women are expected to cover their hair (scarves are often available at the entrance). Photography is usually allowed outside and inside when prayers are not in session, but discretion is expected. The site can be visited year-round, though spring and autumn are the most comfortable seasons. Accessibility is generally good around the square, but interior spaces may feel tight during busy times, so early mornings are best for a quieter visit.
