Üsküdar: three Sinan mosques and the Maiden's Tower
Three Sinan mosques across the water, ending on the sahil with the Maiden's Tower at golden hour. This is a Claude-drafted route awaiting the editor's walk.

1. Üsküdar İskelesi
Ferries from Eminönü, Karaköy, Beşiktaş, Kabataş — pick the route that fits the day's wind. Marmaray and the M5 metro also stop here. Step off the boat and Mihrimah's domes are directly in front of you.

2. Mihrimah Sultan Camii
Sinan's 1547 mosque for Suleiman's daughter — the legend that he was in love with her gives the building its faint sadness, true or not. Single dome, square plan, the simplest of his major works and arguably the most poignant. Free, working mosque; off-prayer hours quiet enough to circle slowly.

3. Atik Valide Camii
Sinan's later complete külliye for Nurbanu Sultan, a fifteen-minute climb up into Toptaşı. The mosque is the centrepiece, but the surviving medrese, hospital and hamam around it are the rarer thing — tourism never came here, so the complex still feels lived-in. Worth the climb.

4. Şemsi Paşa Camii
Sinan's smallest mosque, built in 1580 right at the water's edge — so close that, by tradition, birds don't roost on its roof. The courtyard wall is the Bosphorus. Stand on the sea-side terrace; this is the shoreline Üsküdar had before reclamation.

5. Salacak sahili — Maiden's Tower viewpoint
Walk south along the sahil to the wider promenade at Salacak. Kız Kulesi sits a hundred metres offshore on its small islet — current 18th-century, foundations Byzantine, the legend about a princess locked there to escape a prophecy older than both. Best at golden hour, when the tower catches the last light and the European shore is already in shadow.

6. Back at Üsküdar İskelesi
Ferries back to Eminönü roughly every fifteen minutes. The Marmaray crosses under the Bosphorus in four minutes if you're in a hurry, but the boat is the way to end this walk.
