If you chance to pass by on your way from Ruse to Silistra you will see a large military cemetery beside the road. Stop and have look at the rows of graves, the chapel, the old machine guns, and the monument in the shape of a war medal. There is an obelisk, too, with inscriptions repeating the same words in Bulgarian, German, Turkish and Romanian: "Honour and glory to those who knew how to die heroically for their fatherland."
Strange proportions, unusual materials and extravagant designs: quirky sculptures can be found all over the world, and Bulgaria is no exception. In addition to the monumental angular creations of Socialist Realism and the sometimes traditional statues of historical figures, a number of other statues exist in the country, attracting the attention, the ridicule or the fury of passers-by. Many of these somewhat ridiculous monuments, however, were produced with very serious aims in mind. Some of them commemorate a prominent figure, a historical event, or a local curiosity.
A legend is told all over the Balkans about a bridge and a stonemason. Once upon a time, a group of builders was commissioned to construct a bridge over a river, but whatever the men had built during the day was mysteriously destroyed during the night. Each morning the builders had to start from scratch.
Finally, the men saw the writing on the bridge, and realised that it wanted a human sacrifice. They reluctantly made a deal among themselves: on the following day, they would inter in the bridge the first person who came near.
Pomorie, a seaside town about 20 kilometres north of Burgas, has now become a concrete labyrinth of high-rise hotels and apartment blocks thronged with Russian tourists and holiday-home owners. It does not sound particularly appealing – but that's only on the surface.
Amidst the dust, sun and crowds of Pomorie, there is a place of eternal silence and an unexplained mystery. To find it, you have to take a sign-posted lane off the congested Burgas-Nesebar road. This lane leads to a lush vineyard and there, hidden inside the cold embrace of a huge mound, is a tomb.
Black winter birches cover the steep slope, their naked skeletons creating a colonnade which hides the foot of the hill, so the creek running there is only heard, not seen. White mist rises from the ravine, red leaves cover the ground. All around are more trees, more hills, more mist: this secluded landscape in the Rhodope, beyond the now disused barbed-wire fence which, under Communism, sealed off the border with Greece, stretches to the horizon.
Comfortably spread out on a narrow plateau overlooking the dramatic landscape of Veliko Tarnovo, the traditional village of Arbanasi is something of a conundrum. It is an architectural heritage site, yet it is filled with mansions and hotels in dubious "traditional" style, all built in the past 15 years.
The busy Władysław Warneńczyk Boulevard is the road you need to take through Varna to reach the Sofia-bound motorway. It is also the road to one of Bulgaria's strangest and most moving museums.
Among the firs of the park – an oasis of calm amidst the urban buzz – two Thracian burial mounds stand. One of them, adorned with a monument, encloses a burial chamber where lies the stone effigy of a medieval knight.
A medieval knight? In Bulgaria?
"To the Small Basilica, please," we say to the taxi driver we hail in the centre of a warm, autumnal Plovdiv. Then we realise. The driver is very unlikely to know the whereabouts of Bulgaria's latest archaeological museum, only one day after the official opening.
The massive stone crosses that centuries ago used to be the graveyard of Garlo village, in the region of Pernik, poke out from the undergrowth, a poignant sight that we have covered several times in Vagabond.
This time we are in this picturesque, atmospheric and overlooked part of Bulgaria for another reason: to search for one of this country's most enigmatic archaeological finds.
When you see Karlukovo, near Lukovit, for the first time, you'd be hard put to believe that you are in the part of Bulgaria richest in karst rocks. The settlement lies among low, monotonous hills and there's nothing – not even a signpost pointing to a tourist sight to indicate that underneath this modest landscape lies a labyrinth of caves. It is the result of thousands of years of action by wind and water, which carved the pliable karst rock and formed caves, magical shapes and whirlpools.
