Blazon house in Chiojdu, Buzău, Historic monument in Chiojdu, Romania.

The Blazon House is a historic building in Chiojdu displaying eight coats of arms on its facade, with a central double-headed eagle as the focal point. The structure combines stone foundations with oak-framed walls typical of traditional Romanian construction.

The house was built in 1760 by the Izbășoi boyars and restored only once in its existence. In 2013 it passed into the ownership of the Union of Architects of Romania, which began a restoration with European funds completed in 2015, when the house opened to visitors.

The house is to become a museum of traditional art from the Buzău Mountains and a summer camp for architecture students, following its 2015 restoration. Its style, which influenced buildings in Buzău such as Casa Vergu-Mănăilă and the Conacul Trandafirilor restaurant in Crâng Park, is reproduced on the Romanian 10 lei banknote.

The house stands behind the village school in Chiojdu, Buzău County. It opened to visitors in 2015 after a European-funded restoration by the Union of Architects of Romania, which has owned it since 2013. Check locally before travelling, as opening depends on the museum project and the architecture summer camp held there.

The house's style was copied in Buzău town, at Casa Vergu-Mănăilă and the Conacul Trandafirilor restaurant in Crâng Park, and it appears on the Romanian 10 lei banknote. The Izbășoi boyars built it in 1760; it was restored once, passed to the Union of Architects in 2013, and reopened in 2015.
