Üsküdar holds some notable Islamic monuments. Its most obvious mosque, İskele or Mihrimah Camii, sits on a high platform, fronted by an immense covered porch, opposite the ferry landing on İskele Meydanı. Designed by Mimar Sinan and built in 1547–48, it’s the only Ottoman mosque with three semi-domes (as opposed to two or four), thanks to the requirements of a difficult site against the hillside behind.
Directly across the square, the Yeni Valide Camii was built between 1708 and 1710 by Ahmet III in honour of his mother. It’s most readily identified by the Valide Sultan’s green, birdcage-like tomb, whose meshed roof was designed to keep birds out while allowing rain in to water the garden tomb below.
