Mustafapaşa, formerly known as Sinasos (Greek: Σινασός), is a town(belde) in the Ürgüp District of Nevşehir Province, Turkey.

And other being named after a local hero called Mustafa Pasha, who got a well drilled to the village to solve its fresh water problem.

Since it was hard to make a living in Central Anatolia, many Sinasos Greeks migrated to Constantinople/Istanbul at this time and made a name for themselves as traders in seafood, especially caviare.

Often they sent money back to their families in Sinasos and some of this was used to build the grand mansions that still survive in the town (and are rapidly being converted into hotels).

Its upstairs floor contains one of the secular murals which are a feature of both Ürgüp and Mustafapaşa, and which live on as a reminder of the lost minority populations.

[5] In the town centre, the large 19th-century Church of Sts Helena and Constantine, with a grapevine carved around its entrance, is another reminder of the lost populations.
