The square-shaped structure included four bastions, nicknamed "Smaragd", "Perle", "Rubin", and "Diamant". Smaragd was involved in an ecclesiastical controversy in 1263. Smaragd made serious efforts to avoid a bloody civil war in Hungary. Smaragd was elected as his successor in the first half of 1257. As a result, Smaragd excommunicated Amadeus Pok and Irenaeus filed a lawsuit against his superior. By 1253, Smaragd elevated into the dignity of provost of Pressburg (today Bratislava in Slovakia).
