Try to give a list of remarkable catastrophic collapses of architectural structures of all kind, which occured in Czech, Slovakia and Hungary. I know only the collapse of Vysílač Krašov ( http://en.wikipedia.org/wiki/Vys%C3%ADla%C4%8D_Kra%C5%A1ov ), a 347.5 metres tall TV mast in Czech, but I think you know further catastrophic structural collapses.

I know only about terminal destruction on Paris, Orly Airport, but that's not CE obviously:)

Reportedly the deadliest peacetime structural collapse on the Czech soil occurred on October 9, 1928 on the corner of Na Poříčí and Biskupcova streets in the centre of Prague during the construction of 7-story department store. There were 87 workers on the site, 46 of them died. The project was changed and a hotel (now Hotel Harmony) was built there.

V pohřebním průvodu obětí stavební katastrofy v Praze na Poříčí byla nesena trnová koruna s přepravdivým nápisem: KAPITALISMUS VRAŽDÍ DĚLNÍKY!
