RT Journal Article SR Electronic A1 Peřina, Ivan T1 Stronghold in Útěchovice. On research of a medieval smoky room or already a living room JF Průzkumy památek YR 2018 VO 25 IS 1 SP 3 OP 24 DO 10.56112/pp.2018.1.02 UL https://pruzkumypamatek.cz/en/artkey/prp-201801-0002.php AB A triangular set of windows with small upper openings was identified in the Útěchovice Stronghold (Česká Lípa region) along with an imprint of a wooden vault frontage. These discoveries as well as other documented findings remarkably shift the current knowledge about the appearance of a medieval living room. Later analogies raise a question when during the Middle Ages the living space changed from a smoky room into a living room where the stove heat could circulate and ventilate the room through an upper opening and which could also conduct combustion products away from light.
