What they are
Irish round towers (cloigtheach, "bell house") are early medieval stone towers, probably built between the 9th and 12th centuries, usually close to a church or monastery. They were bell towers first, though they may have had other uses. About 120 are thought once to have existed in Ireland; most are ruins, and 18 to 20 are almost perfect.
(Wikipedia, "Irish round tower" ↗)
Counts differ. Wikipedia gives Mayo, Kilkenny and Kildare five towers each, the most of any county. The record counts every recorded site, standing or not, so it has Galway at 9, Clare at 8 and Laois at 6 (Mayo 5, Kilkenny 5, Kildare 5). Some records are for towers destroyed centuries ago or only possibly there; at least one record notes that, according to the Ordnance Survey letters, there never was a round tower at the site.

Before you go looking
- A record is a survey entry, not a promise that something is there. The Sites and Monuments Record lists sites that are known, reported or marked on old maps, including some that have been destroyed, moved, or were never found when inspected. Each record's own description says what the surveyors saw; read it before you set out.
- Some records have no description uploaded yet, and a few have no usable position; they are marked as such.
- Most sites are on private land. Ask before you cross a field, and leave things as you find them: monuments in the Record of Monuments and Places are protected under section 12 of the National Monuments (Amendment) Act 1994 ↗.
- The Sites and Monuments Record covers the Republic only. Northern Ireland's record (the NISMR) is counted here by county from its open data, by matching the record descriptions; it is not listed site by site and its counts are not directly comparable.

Quick answers
How many round towers are there in Ireland?
The Sites and Monuments Record has 85 round tower records in the Republic, and Northern Ireland's record mentions 11. These include stumps, destroyed towers and sites known only from old accounts. Wikipedia says about 120 are thought once to have existed, and 18 to 20 are almost perfect.
Which county has the most round towers?
It depends on what is counted. Wikipedia names Mayo, Kilkenny and Kildare, with five each. Counting every record, including stumps and lost sites, the Sites and Monuments Record has Galway 9, Clare 8 and Laois 6.
