Zisa Palace is Arab-Norman building from 12th century in Palermo.
Admission is 7€ per adult person.
There is some reconstruction outside..
However you can go inside and see almost everything...

Tickets are 6€ per adult person, but you have to buy it in lekáreň u červeného draka which is very interesting pharmacy near Michael's Gate . There is a beautiful view from top. I recomend visit this place..

Well preserved Castle in Dublin. Admission is 8 euros per adult person without guide... You don't need to buy ticket online I think. Especially in the morning.. There is so many paintings inside.. Don't forget to visit garden outside...
