From the Wikipedia: "Nevşehir, formerly Muşkara, (maybe the ancient city of Nyssa, Νύσσα in Ancient Greek), is a city and the capital district of Nevşehir Province in the Central Anatolia Region of Turkey. According to the 2010 census, population of the district is 117,890 of which 85,634 631 live in the city of Nevşehir. The district covers an area of 535 km2 (207 sq mi), and the town lies at an average elevation of 1,224 m (4,016 ft)."
I stayed here the first time I went to see Cappadocia and kind of liked it, until I discovered Ürgüp provided me with a much better springboard for exploring this region. I returned in 2011 on a rainy day, and found the town pretty dismal, though I think the new outcrops (that lie too far from centre to visit at the time) will provide its occupants with nice living conditions. I found one interesting mosque-plus-medrese complex that I liked a lot, and views from the fortress on top of a nearby hill are not bad. It's importance has been increased after a huge underground city was discovered. It cannot be visited yet, and that may remain so for some years.
With some more sun I would probably have liked the town a bit better, but just a bit (during a 2017 repeat visit it again was overcast with some rain; in 2019 I realized that I tend to visit Nevşehir almost always on a day when rain is expected, as on other days I would rather make my walks in nature. As a result my pictures may give the impression this is a very rainy city. I think it is not). Still it is too much of a jumble of uninteresting buildings and busy streets for my taste.
