The relation is misbehaving (building=* on two levels, courtyards not showing properly), so I've asked b-unicycling to have a look at it.

Hi,

way/98613817/

Does Children's Health Ireland occupy the bulk of the hospital? I thought that there were lots of other departments, but that it was a step down in sophistication compared to Beaumont, Mater, etc,

Hi,

Thank you

Hi,

way/1232285674/

Would you know what the street names are here?

Hi,

way/1098090043
way/1130640427

Duplicated way here with different values.

Hi,

This: way/1323946345 appears to be traffic_calming=bump

Hi,

way/284864403

The buildings here appear to be double-mapped. Changing one set of building=* to building:part=* might solve this.

Hi,

way/1323571493

Is the Lakelands River all underground?

Hi,

node/3399488596

Is this "The High Horse"? Location slightly off.

Hi,

There are about 20 double mapped buildings along the R727, e.g. way/1332092241

I think this is one of those big garden umbrella things: way/1326299049

Hi,

node/12321453984

The road isn't joined up here and is generally a git confused.

Hi,

way/1330684946

This is a turning area, not car parking. They are important for rubbish trunks, deliveries, etc. Marking them as parking only encourages inappropriate behaviour.

Hi,

way/1206277449/history

What is this?

Hi,

Welcome to OSM.

Could I ask what this line represents? way/1327928609

Hi,

way/1317963376

What is this line?

I was going to suggest splitting it into two buildings, but then I saw there are three courtyards.

I;ve consolidated most of the amenity=social_facility rags into the site.

Hi,

way/935851540

The relations here appear a bit confused. There might be more than one relation for the same building and more than one nursing home object.

Hi,

way/1326463120
way/1326463708

Duplicate buildings with slightly different details.

That's an abuse of the tagging.
