>Prefer to see castles.
The term 'castle' is often misleading. I suspect you are thinking of Medieval stone castles (1100s > 14/1500s) but both Iron Age fortified settlements and large private houses built in the 1700s/1800s (often with towers, battlements etc) can be called 'castles'.
The island of Ireland
(which is actually two separate countries), like mainland Britain, once had thousands of Medieval castles. But the majority no longer exist or are in ruins (i.e. very little to be seen). Northern Ireland
has some excellent Medieval castles but I'll concentrate on the Republic of Ireland
because that is what I assume you mean by 'Ireland'.
A few castles in the Republic have been restored and are now major visitor attractions (e.g. Bunratty Castle & Folk Park
, Blarney CastleKilkenny Castle
), quite a lot (whether Medieval in origin or not) are now luxury hotels (e.g. Clontarf Castle Hotel
, Ashford Castle
) and others are open to the public but less well-known (e.g. Trim Castle
, Cahir Castle
There are of course a range of organised tour operators so it's really a matter of looking at their itineraries and seeing if any appeal. The official Irish Tourist Office lists them:https://www.ireland.com/en-us/touroperators/
Most large and small-group tour operators, whether 'luxury' or not, offer the visits per tour which will maximise their potential clientele. So you can expect such tours to include only one or two castles/'castles' (usually the most visited) or even none at all.> I am prepared to pay a little for luxury
You could investigate tour operators which offer private 'castle tours': e.g. https://www.irishtourism.com/castles-and-manors
If budget isn't a problem you could set your own itinerary with a private tour. There are several operators listed on the site above e.g. https://www.privateirishtours.com/
There are also operators who will help you organise your own independent trip and sort out your accommodation, so you can drive yourself and include the castles and historical sites & sights you want to see.
Or you could organise it all yourself, planning your own itinerary, booking your accommodation online (very easy with e.g. www.booking.com
) , using public transport or driving yourself to the places you *really* want to see.
History is my primary interest so I'd choose the last option....and have done so more than once. :-)
