Excavations at the Capitular Church of SS Peter and Paul at Vyšehrad in Prague, the second most prominent basilica of the P?emyslid state, have been conducted by the Institute of Archaeology in Prague since 1966. The entire exterior ground area of the church was excavated from 1968-1991, while the interior of the contemporary church was investigated in 1981-1985. Seven construction periods were recorded, the oldest being romanesque from the times of the foundation of the church by the prince and first King of Bohemia, Vratislav II (1061-1092). The following reconstructions were held by Sob?slav I, Eliška P?emyslovna, the last P?emyslid queen, and finally Charles IV. The last of the structural changes imprinted upon the church a High Gothic character which can be compared with the southern French basilicas (Toulouse, Narbonne). The volume not only summarizes the results of the archaeological investigation but also presents data gained by analyses of glass and tiles, and by anthropological, archaeozoological, petrological and dendrochronological research.
