Hagia Sophia and Blue Mosque: Differences, Things to Know & Combo Tickets

If you're planning a trip to Istanbul, two of the most iconic landmarks you'll hear about are Hagia Sophia and Blue Mosque.

With their grand domes, minarets, and rich histories, it's easy to see why travelers often confuse the two. Are they the same? Which one should you visit first? Can you see both in one day?

Let’s break it down.

Hagia Sophia and Blue Mosque Differences, Things to Know & Combo Tickets

Are Hagia Sophia and Blue Mosque the Same?

No, they’re not the same — though they do share a lot in common. Located just a few hundred meters apart in Istanbul’s Sultanahmet district, Hagia Sophia and Blue Mosque have become symbols of the city. But they’re two distinct buildings with very different stories.

  • Hagia Sophia was originally built in 537 AD as a Byzantine cathedral, later converted into a mosque, then a museum, and recently reconverted into a mosque in 2020.
  • The Blue Mosque (officially Sultan Ahmed Mosque) was built in the early 1600s as an Ottoman imperial mosque and still functions as one today.

So while both are active mosques now, they were built nearly a thousand years apart and reflect different eras of Istanbul’s past.

Difference Between Hagia Sophia and Blue Mosque

While both landmarks are impressive, their differences are easy to spot once inside.

Hagia Sophia presents a more historical and architectural journey. Visitors are struck by the scale of its dome, the remains of Christian mosaics, marble pillars, and Arabic calligraphy. It feels more like a historical monument, layered with stories from different eras.

In contrast, the Blue Mosque offers a more serene and unified space. Its symmetry, cascading domes, and richly tiled interior give it a unique charm. With its six minarets — an unusual feature when it was built — the mosque was meant to assert the prestige of the Ottoman Empire.

Visitors often describe Hagia Sophia as “monumental” and the Blue Mosque as “graceful.” Both are beautiful, but in very different ways.

Distance Between Hagia Sophia and Blue Mosque

One of the most convenient aspects of visiting Hagia Sophia and Blue Mosque is how close they are to each other. Both are located in Istanbul’s historic Sultanahmet district, with only a large pedestrian plaza — Sultanahmet Square — separating them.

  • Walking distance: About 250 meters (roughly 3–4 minutes on foot)
  • Route: Simply exit one building, cross the square, and you’ll find yourself at the entrance of the other.
  • Accessibility: The area is flat and paved, making it walkable even for families, seniors, or those with mobility concerns.

Because of this, many visitors choose to explore both landmarks back-to-back, often within the same morning or afternoon. The proximity makes them ideal for walking tours that also include nearby landmarks like the Basilica Cistern and Topkapi Palace.

*Visit early in the day to avoid crowds, especially during peak seasons. Early mornings also offer softer light for photos and a quieter atmosphere.

Hagia Sophia or Blue Mosque: Which Should You Visit First?

Since both landmarks are located just a few minutes apart in Sultanahmet, you can easily visit them in one trip. However, if you only have time for one of these two, we recommend visiting Hagia Sophia.

If you’re planning to visit both, it’s generally recommended to start with the Blue Mosque, as it is often closed to tourists during prayer times. Visiting early in the morning gives you the best chance of seeing it without interruptions and before large tour groups arrive.
