The T-pillars
The central pair in Enclosure D stands about 5.5 metres, and carved arms and hands on some pillars show they are stylised humans, not mere stones.

On a bare rise above the Harran plain, a short drive north-east of Şanlıurfa, stands some of the oldest monumental architecture anyone has found: rings of T-shaped limestone pillars raised around 11,500 years ago, some six to seven millennia before Stonehenge or the pyramids. The people who carved them were hunter-gatherers on the threshold of farming who had not yet taken up pottery, yet they cut foxes, snakes, boars and scorpions into the stone. The enclosures were later swallowed by rubble and soil; the excavators long believed they had been deliberately buried, though that idea is now disputed. The Turks call it 'the zero point of history'; UNESCO inscribed it in 2018. The visit is tightly choreographed. You buy your ticket at the visitor centre at the foot of the hill, a shuttle bus takes you the last stretch up to the dig, and you circle the four main enclosures on a raised wooden walkway under a vast membrane roof. You will not touch a pillar or step down among the stones, and the central monoliths of Enclosure D, roughly 5.5 metres tall, look smaller from the boardwalk than the photographs suggest. Only about a tenth of the site has been excavated; geomagnetic surveys point to at least twenty more enclosures still under the soil. Getting here from Şanlıurfa is easy: about 18 km north-east of the city, 25 minutes by car or taxi on a good road. A municipal bus (route 0) leaves hourly from outside the Archaeology Museum and takes about half an hour, but services are sparse, so most visitors choose a hire car, a taxi by the hour or an organised tour, which usually pairs it with Karahantepe. Admission is EUR 20 for foreign visitors, and the site opens daily 08:30–19:00 in summer, closing earlier in winter. In August, Urfa passes 40°C and the only shade is the roof itself, so come at opening or in the last two hours. The walkway is level and pushchair-friendly once you are off the shuttle, but children tend to tire of a site you look down on rather than walk through. The best things dug from this hill are not here: the 'Urfa Man' statue and a full-scale replica of Enclosure D sit in the Şanlıurfa Archaeology Museum in town, and it pays to see them before the hill rather than after, so you understand what you are looking at.

A full circuit above Enclosures A to D on a raised boardwalk; the light is best in the first hour after opening, before the coaches arrive.
Karahantepe, roughly an hour's drive to the east, has pillars cut from the living bedrock and a fraction of the visitors; admission was free at last check, but it is sometimes closed to visitors, so ask before driving out.

With one day, Göbekli Tepe plus the Şanlıurfa Archaeology Museum in town is the right order, since the museum explains what you see on the hill. With two days or your own car, add Karahantepe: far fewer people, pillars still standing in the bedrock they were cut from, and no admission charge at last check, though you should confirm at the Göbekli Tepe visitor centre that it is open before making the drive.
Honestly, the actual viewing takes about forty minutes and the thrill is intellectual more than visual; anyone unmoved by the idea that these are among the oldest temples on earth may leave saying 'just stones'. If the idea does move you, it is among the greatest things to see in all of Turkey, and nothing else feels like it.
