I honestly expected quite a bit of this site. Afterall these monasteries are widely regarded as some of the best orthodox works. I really hoped I wouldn't find some minor remains or worse yet repainted frescos.
I was very pleasantly surprised. These monasteries rank among the most beautifull I've ever seen. They are surprisingly monumental, with high ceilings; and they're covered in magnificent frescos. The structure IS also quite particular, with high square columns used as canvases. If I had to note a downside is that they feel somewhat like a testament to the past and not part of a living tradition. The churches are somewhat cold, with no incense and no candles.
Now onto the specifics. I was Lucky to visit all 4 locations of the site, though I could not enter the churches in Prizren. Here's my overview of them:
Gračanica: It's sits just un the outskirts if Pristina. you'll know you're arriving when you start seeing serbian flags. I didn't check, but It very much looked like there was an important serbian community centered around the monastery. Here we encountered one of the most shocking side about visiting this site. All these churches are walled with barbed wire. In 2014 hundreds of monasteries, including some in this site, were burned. Since then they're all protected, mainly by the KFOR. Gračanica turned out to be a beautifull Monastery.
Prizren: as notes I did not visit the interior of Prizren's churches (which were burned). The city was somewhat disapointing. I found the mosques somewhat baroque style offputing and the centre quite genérico though well kept.
Dechani: this is the jewel of the nomination and It's made clear by the strict KFOR check up you must do before entering. The exterior I found very interesting, reminiscent of churches in Italy and croatia (especially sibenik) with Its ellegant marble exterior. The interior IS amazing, more impressive than that of Gračanica though quite similar.
Peč: I did not read much about this site, but I know Peč holds an important role in the serbian orthodox church. This is evident from the size of the complex, of which unfortunately only one main church and a small parrish have been preserved. The church is quite interseting. I especially liked the barrel vault decorated with frescos.
All in all, It's easy to see the OUV of these monasteries. I haven't seen any orthodox ones this espectacular in the balkans (though i haven't visited Rila). The best way to visit IS probably by car, as some of the churches seemed quite inaccesible.
