Roche Clarecastle

Roche Ireland Limited (Clarecastle) is a subsidiary of the Roche Group,

based in Basel, Switzerland.


Roche’s Clarecastle facility was established in 1974 as Syntex Ireland on

36 hectares of land overlooking the Fergus River in Clarecastle, Co. Clare,

and became Roche’s pharmaceutical manufacturing facility in Ireland when

the Roche Group acquired the site in 1994.


Following a decision in 2015 to exit the Clarecastle facility, final

production was undertaken in November 2019 and pharmaceutical operations

ceased in March 2020.


A planning application to decommission the site was submitted to Clare

County Council in June 2020 and a formal final grant of planning permission

to commence work on the phased demolition of all existing buildings,

structures and infrastructure, on, in and under the site of the existing

Roche pharmaceutical plant at Clarehill, Clarecastle, Co Clare was issued

by Clare County Council on 3 February 2021. This work is now underway and

will continue in phases through to mid 2028, when the groundwater

validation monitoring phase is complete and the site's EPA licence is

officially surrendered.
