Unknown appearance of the royal castle in the early 17th century iconography DP - 2017 Jun 15 TA - Staletá Praha PG - 120--143 VI - 33 IP - 1 AID - 10.56112/sp.2017.1.05 IS - 02316056 AB - The University Library in Bologna possesses a plan dated circa 1626, by the Florentine architect and military engineer Giovanni Pieroni, concerning proposed fortification with a contemporary survey of Vyšehrad castle, drawn in particular detail in the area of the ruined former royal acropolis prior to its Baroque redevelopment to a fort, providing a valuable glimpse of the earlier constructions. Additionally the plan depicts elements not revealed from the archaeological excavations, comprehensively published in 2004-2015. Also prospects by the Dutch draftsmen, Roelandt Savery and Paulus van Vianen, who worked in Prague at the court of Rudolph II, are equally valuable for the topography of Vyšehrad. These documents help to interpret other known iconographic sources, mainly the two Sadeler's prospects from 1606, and depict the royal acropolis in greater detail. They also bring new knowledge of its layout in the period of Charles IV and Wenceslas IV, especially regarding the questions about its gates and palaces.
