This article charts the history of a mid 19th-century Haram mausoleum in Surabaya, East Java. Officially known as the mausoleum of the Haram saints Muhammad b. Aydar<umacron>s al-Habash (d.1919) and Muhammad b. Ahmad al-Mihr (d.1926), the site has been a popular destination of Indonesian Muslim pilgrims. A close inspection of the inscriptions on the other tombstones in the mausoleum, however, reveals that the edifice was actually built in honour of Pangeran Hasan b. Umar al-Habash (d.1854), a wealthy Haram entrepreneur and diplomat who served the Dutch colonial authorities. This article observes the processes through which the family mausoleum of the Pangeran became known as the mausoleum of two saintly figures. It argues that the interment of the saints in the mausoleum initiated discursive and liturgical developments that resulted in its transfiguration into a devotional site with new histories that gradually eclipsed its earlier identity. Such developments included the production of hagiographic texts and the institutions of ritual practice and commemorations, all of which inadvertently neglected the mausoleum's prior history and inflected its identity.
