The birthplace of Collins should have a proper interpretive centre

I write to thank you on behalf of my three friends (history buffs) and myself from the United States who have been on holidays this past week in this wonderful part of Ireland called Cork City and county.

Your city is remarkable, it is not a large city by any means but what an amount of history it contains with that English Market and the Coal Quay, the churches, cathedrals and museums.

On a guided tour, we learned that the Vikings actually set up the original city of Cork but I am wondering if I got that wrong since there is nothing to back up that claim in the literature I picked up.
