Bojentsi's designation as an architectural reserve means the entire village is essentially an open-air museum of Bulgarian Renaissance domestic architecture. The roughly 120 houses lining both banks of the Bojanka river date predominantly from the late 18th and early 19th century — a period of considerable prosperity for Bulgarian craftsmen and traders, even under Ottoman rule.
The characteristic style is immediately recognisable: stone ground floors, timber-framed upper stories that overhang the lane, small windows with wooden shutters, and exterior walls sometimes decorated with naive frescoes of the houses' owners. Several of the finest examples are open as museums, giving you a look inside the carved wooden ceilings, the sunken fireplaces, and the decorated plaster niches that defined a comfortable Bulgarian household in the 1820s. The lanes are cobbled throughout and best explored on foot — the whole village takes perhaps an hour to walk.
