hi
here is some information you might be interested in

town asylum:ST. COLUMBAS/COLUMBUS used to be a very scary looking place now it is a hotel owned be a well known hotel chain (still looks a bit scary!!). more recently built hospital (20-30yrs) same name near by.
i am not too sure about this one: NAZERATH NOME it always held a bit of mystery for kids as for what is was used for. STILL IN USE
outside the town: CLOONAMAHON ( A MIXTURE OF THE ABOVE TWO ). STILL IN USE.
I COULD FIND OUT A BIT MORE IF YOU NEED IT. LET ME KNOW.
