Ostrava and recommendations in Czech Republic

[ginswinger]

We've been a few times to Czechia particularly to Pardubice, Brno, Kutna Hora and Prague but wondering if Ostrava is interesting? Does anyone else have gems they would like to share?

I don't know Ostrava, but I did like Olomouc. And in that general area Kroměříž is particularly beautiful (it's a Unesco heritage site), with the Archbishop's Palace and grounds.

And if you want a peaceful break, Luhačovice is a gorgeous spa town set in a lovely valley.

Thanks @CardinalSin great tips!
