Here in NL we have a few stubs (of the Schiphol CTR) that extend from 1200' upwards.
That would explain Jan's confusion then.
I found a chart of the Schiphol airspace
here, and they are calling them all CTRs, and arranging the airspace like this
TMA TMA TMA TMA TMA
....CTR2CTR1CTR3....
........CTR1........
vs
TMA TMA TMA TMA TMA
....CTA CTA CTA....
........CTR........
or
TMA TMA TMA TMA TMA
....CTA CTR CTA....
........CTR........
which are both used in the UK. So I'm not sure which is the ICAO way of doing it.
