1382, 1385 and 1424 A royal wedding, and a castle for queensKráľovská svadba a hrad pre kráľovné

The castle was finished in 1382, and it was finished for an occasion: the betrothal of Louis's daughter Mary to Sigismund of Luxembourg was settled here, and the wedding itself is placed at Zvolen in 1385. Sigismund was about seventeen. He went on to rule for half a century as king of Hungary, king of Bohemia and Holy Roman Emperor, and he came back to Zvolen again and again — this was a house he liked. In 1424 he settled the castle estates of Zvolen county on his second wife, Barbara of Cilli, as her dower: the property whose income paid for a queen's household. Zvolen, Ľupča, Vígľaš, Dobrá Niva and Šášov were all on that one list.Hrad dokončili v roku 1382 — a dokončili ho na príležitosť: dohodli tu zásnuby Ľudovítovej dcéry Márie so Žigmundom Luxemburským a samotnú svadbu kladú pramene do Zvolena v roku 1385. Žigmund mal vtedy asi sedemnásť rokov. Vládol potom pol storočia ako uhorský kráľ, český kráľ i rímsky cisár a do Zvolena sa vracal znova a znova — tento dom mal rád. V roku 1424 zapísal hradné panstvá Zvolenskej stolice svojej druhej manželke Barbore Celjskej ako veno, teda majetok, z ktorého žil kráľovnin dvor. Na tom jedinom zozname boli Zvolen, Ľupča, Vígľaš, Dobrá Niva aj Šášov.
