When the names of the churches were forgotten, the villagers gave them new ones. The Letters. God's Gully. The Buried Church. One they called simply The Church, a name so stripped of detail it somehow contains everything that had been lost. Centuries of monastic life, a scriptorium full of manuscripts, royal burials, eight hundred monks – all of it reduced, in the end, to a name that was really just a gesture toward something irreplaceable and gone.

Steep rocky peaks, pristine alpine meadows, hidden lakes and some of the last communities that herd semi-wild, traditional breeds of sheep and horses: the Pirin is a small mountain that is one big wonder of nature. However, the sublime beauty of the mountain, whose highest parts have been a UNESCO-listed national park for over four decades, is not for those who would rather eschew hiking or stick to skiing in Bansko.

Authenticity, genuine patterns and natural materials are all the rage in interior design today. Current trends are all about handcrafted products that are beautiful to look at, do not pollute the environment and are not harmful to your health with microplastics and dust-generating synthetic materials. Finding such interior products is not easy. But in a small town in Bulgaria you can find a surviving tradition that for centuries has produced amazing hand-woven carpets in stunning designs, using real wool and natural dyes.

What happens after death has fascinated people since the dawn of humanity. The earliest accounts of what they thought was the answer paint a glum picture. According to the ancient Mesopotamians, the dead inhabited a grim realm where they had only dust to eat and drink. Ancient Egyptians striving for an afterlife had to be mummified and to undergo a strict vetting process, under threat of being eaten by a monster in case they failed. The ancient Greeks were aware that even the greatest heroes would be reduced to nameless shadows in the Kingdom of Hades.

Of all UNESCO World Heritage sites in Bulgaria, Madara Horseman is most difficult to see.

This is not because Europe's only medieval open-air relief is in an isolated spot that is hard to reach. The Madara Horseman is a short and easy drive from the Hemus motorway, near Shumen. Just beneath the 100 metre high rock where it is carved, there is a new visitor's centre and a viewing platform.

Bulgarians are proud of the period of their national revival, in the late 18th and 19th centuries. It established the country as a young and energetic nation eager to restore its statehood after five centuries of Ottoman domination. Personalities such as the revolutionaries, Vasil Levski and Hristo Botev, are the poster boys of the era, but the whole revival period, which spans a century, was more complex. Violent revolution against the Sultan was only a part of it and would have been impossible if Bulgarians had not already emancipated themselves culturally, economically and politically.

A pair of dark, tender eyes glow in a delicate face crowned with a costly headdress decorated with pearls. The lady's lips are slightly curved, as if she is smiling at a private joke, or perhaps a secret she holds? The woman herself is an enigma. We know that the elegant lady painted on the walls of the Boyana Church was called Desislava and that she was the wife of Kaloyan, the handsome lord of 13th century Sofia painted next to her. But why is Desislava smiling?

If you visit Nesebar in high season, it will be easy to doubt the wisdom of UNESCO's 1983 decision to inscribe this town on the Black Sea coast into its World Heritage list. The crowds of holidaymakers on day trips from the overdeveloped resorts around, the stalls selling trinkets and souvenirs, the chalga music booming from overpriced, "traditional" restaurants are so overwhelming you cannot enjoy – or even notice – the beautiful medieval churches and the old wooden houses that are the reason all of these people and businesses are here.

There is a silver lining to the sharp decline in international tourism in Bulgaria in 2020. You can now see Nesebar, one of this nation's most impressive towns, without hordes of Brits and Scandinavians still hungover from the previous-evening's pub crawl at Sunny Beach resort.
