Here is a view from the grounds of the Süleymaniye Mosque, which sits atop one of Istanbul’s seven hills. The view across the Halıç (or the Golden Horn) to Beyoğlu includes Galata Tower (upper right). This mosque, completed in 1557, is another work of master Ottoman architect Mimar Sinan. To read more about Sultan Süleyman (the Magnificent), look here and here.
Süleymaniye Mosque
The Golden Horn
This is the Golden Horn (Haliç) as seen from the Pierre Loti cafe in Eyüp. (There is a cable car going up to the cafe, but it is more fun to climb up through the mezarlik). From here you can see some of the structures on Sultanahmet (the historic peninsula). In the distance on the left is the Aya Sofya; to the right is the Süylemaniye Camii. The dark blob above the bridge at the skyline is a butterfly, which had photobombed the picture. It looks to be a Red Admiral (Vanessa atalanta).
Minarets and moon
These minarets are from two different mosques (same evening, same moon). The one on the left is the Süleymaniye Camii, the one on the right is the Yeni Camii. Both of these mosques are on the historic peninsula. The Süleymaniye Mosque was built in 1550-58 by Mimar Sinan. The New Mosque (Yeni Camii) was built in 1660-65 by Davut Ağa, an apprentice to Sinan. (There will likely be pictures of the interiors of these mosques at a future date, so stay tuned. I know you will).
