Mihrimah Sultan Mosque and Yeni Valide Mosque: Üsküdar's two imperial mosques

Two mosques on Üsküdar's waterfront, a few minutes apart

Mihrimah Sultan Mosque and Yeni Valide Mosque are two working mosques in Üsküdar, the district that faces Sultanahmet across the Bosphorus from Istanbul's Asian shore. Both stand close to İskele Meydanı, the square by Üsküdar's ferry pier, a short walk from each other, though they were built more than a century and a half apart by different architects for different women of the Ottoman court.

Neither mosque is part of Istanbul's UNESCO World Heritage listing. UNESCO's own record for the Historic Areas of Istanbul property lists four component areas — the Sultanahmet archaeological site, the Süleymaniye conservation area, the Zeyrek conservation area and the Istanbul land walls — all on the historic peninsula on the European side, and it makes no mention of Üsküdar or any site on the Asian shore.[14]

Mihrimah Sultan Mosque (İskele Camii): Mimar Sinan's first Üsküdar commission

Kanuni Sultan Süleyman had this mosque built for his daughter Mihrimah Sultan. According to TDV İslâm Ansiklopedisi, the architect was Mimar Sinan, and the mosque was one of his first important building groups after he became chief court architect, raised at the same time as his Şehzade complex on the other shore.[1] Work began in the early 1540s and TDV reads the completion inscription over the main gate as Dhu'l-Hijja 954, which converts to 1547.[1]

A second reading gives a different year. The Istanbul Metropolitan Municipality's cultural-heritage record reads the same Hijri inscription date as "Zilhicce 954 / Temmuz 1548" — July 1548. XTOUR is not in a position to adjudicate between the two conversions of the same Hijri date and gives both here rather than picking one.[12]

Sinan's plan carries the central dome on half-domes on three sides, leaving the entrance side without one — a departure from the four-half-dome scheme he used at Şehzade, which TDV attributes to the site rather than a change of approach.[1] Of the wider külliye, which originally also held an imaret, a caravanserai, a hospice and cisterns, only the mosque, a medrese and the elementary school (sıbyan mektebi) survive; the municipality's heritage record adds that the medrese was restored in 1961 and converted into a health centre, losing its original interior.[12]

The Üsküdar district governorship's own page on the district's imperial mosques adds a detail worth knowing before you go: in April and May the sunrise appears between the mosque's two minarets, and the governorship connects this to the meaning of the name Mihrimah, "sun and moon."[9]

For visiting: the mosque stands in a wide outer courtyard reached by steps from the shore road. The Ministry of National Education's out-of-school learning portal gives the address as Paşalimanı Caddesi No:2, Mimar Sinan Mahallesi, and lists the mosque as open to visitors every day, all day — a portal default rather than the mosque's own published hours.[7] That portal does not state an admission fee, and XTOUR found none stated elsewhere; because this is a working mosque, treat the day's prayer times, not any fixed timetable, as what actually decides when you can go in.[7]

The portal's visitor notes ask visitors to dress in a way that suits a mosque, to use the headscarves and wraps kept at the entrance, to keep their voices down, and not to walk in front of anyone praying.[7] The Directorate General of Foundations (Vakıflar Genel Müdürlüğü), which lists the building as a Mihrimah Sultan Vakfı property, states that it has been restored and is open for worship, giving 2014 as the restoration year; XTOUR found no official page with fuller restoration dates or scope.[6]

Yeni Valide Mosque (Valide-i Cedid Camii): built for a sultan's mother, a century and a half later

Yeni Valide Mosque, also recorded as Valide-i Cedid Camii, was built for Gülnuş Emetullah Sultan. According to TDV İslâm Ansiklopedisi, construction began on 7 November 1708 and the mosque opened for worship on 5 March 1711 — well over a century after Mihrimah Sultan Mosque.[2] The Üsküdar district governorship names her as mother to two sultans, Mustafa II and Ahmed III.[9]

Some official pages, including the district governorship's own list of Üsküdar's imperial mosques, name the court architect Kayserili Mehmed Ağa as the builder.[9] TDV is more cautious: it says it is not known for certain that he designed the complex, so this guide does not state an architect as settled fact.[2]

The prayer hall is close to square in plan under a central dome that reads as low because of the windows set into its drum, rising in stages rather than the single pyramid of a classical Sinan mosque — TDV places the design near the end of the classical Ottoman style, into the early Tulip Period. The courtyard, unusually, is larger than the prayer hall itself, ringed by domed arcades around an octagonal marble ablution fountain; TDV singles out the carved stone birdhouses set into the outer walls as among the earliest examples of their kind and reads them as a sign of Ottoman care for animals.[2]

A survey of the site by Kültür Envanteri places the whole complex between Hakimiyet-i Milliye Caddesi, Balaban Caddesi and İmam Nasır Sokağı, in the middle of Üsküdar's market district, and names the courtyard's five gates: the Market Gate, the Bit Bazaar Gate, the Arasta Gate, the Balaban Gate, and a fifth gate known by several historical names.[10]

The Ministry of National Education's visit portal gives the address as Hakimiyeti Milliye Caddesi 10/1, Mimar Sinan Mahallesi, and lists the mosque as open to visitors every day, all day — again a portal default rather than the mosque's own published hours.[8] Unlike the Mihrimah Sultan Mosque page, this one states explicitly that entry is free.[8]

The portal asks visitors to dress appropriately, to remove their shoes where indicated, to keep a quiet and respectful manner, and not to touch the historic fittings, and it gives the phone number of the Üsküdar Müftülüğü (district mufti's office) as 0216 553 07 82.[8] That number matches the one published on the mufti's own Diyanet page, which also gives its address as Salacak Mahallesi, Doğancılar Caddesi No:148, Üsküdar.[11]

One correction: the visit portal's own summary describes the mosque as built "at the end of the 18th century."[8] That conflicts with TDV's dating and the mosque's own foundation inscription, both of which put construction in 1708–1711, so this guide uses the inscription date rather than the portal's summary line.[2]

Not the mosque you might be thinking of

There are two Mimar Sinan mosques dedicated to Mihrimah Sultan in Istanbul, and both carry the identical Turkish name, Mihrimah Sultan Camii. TDV İslâm Ansiklopedisi holds a separate entry for a second Mihrimah Sultan complex at Edirnekapı, in Fatih on the European side, also a 16th-century Sinan design for the same patron but a different building several kilometres away, across the Golden Horn. This guide is about the Üsküdar mosque only.[3]

Yeni Valide Mosque is easy to confuse with another Üsküdar mosque that also has "Valide" (mother-sultan) in its name: Atik Valide Mosque (Valide-i Atik Camii). According to TDV, Atik Valide was built between 1570 and 1579 by Mimar Sinan for Nurbânû Sultan, mother of Murad III, and is described as Sinan's last complete külliye — an older, larger and separate complex from Yeni Valide Mosque, which was built more than a century later for a different sultan's mother.[4]

Yeni Valide Mosque is also not the better-known Yeni Cami ("New Mosque") in Istanbul, the one beside the Egyptian Bazaar at Eminönü on the European shore. TDV records that mosque as begun in 1598 for Safiye Sultan, halted after 1603, and only completed on 30 October 1665, decades later, under a different sultan's patronage — a separate 16th/17th-century building on the opposite shore, which is also sometimes called Valide Sultan Camii, the likely source of the name overlap with Üsküdar's "new mother-sultan" mosque.[5]

Getting there, and visiting both in one outing

Mihrimah Sultan Mosque stands directly on İskele Meydanı, the square at Üsküdar's ferry pier, which sits on Paşalimanı Caddesi — the same street named in the mosque's own address. The terminal is used by the municipal Şehir Hatları ferries, running lines that include Üsküdar–Eminönü, and by the private Dentur ferries to Kabataş and Beşiktaş, so arriving from the European side by boat puts you within a couple of minutes' walk of Mihrimah Sultan Mosque.[13]

Yeni Valide Mosque is a short walk further inland, in Üsküdar's market district. Neither mosque's operator publishes a combined route, opening pattern or joint visitor arrangement for the two, so treat this as two separate stops rather than a single ticketed circuit, and budget time for both to be closed to visitors around prayer, particularly around midday and on Friday.

XTOUR found no marketplace listing specific to either mosque. General Istanbul mosque tours and tickets on Skygate's platform cover Sultanahmet and Süleymaniye on the European side; none of the listings checked for this guide named Mihrimah Sultan Mosque or Yeni Valide Mosque, so no booking link is included here.
