Welcome to the website for the Catholic Parish of Grimsby, Cleethorpes and Immingham, which is under the patronage of the Most Holy & Undivided Trinity!

I hope that you will find this website useful; it will give you a glimpse into everything that is going on in our large and diverse parish.

We have three churches where Mass is celebrated each week: St Mary on the Sea Church in Heneage Road, Grimsby; Corpus Christi Church, in Grimsby Road, Cleethorpes; and Our Lady Star of the Sea Church, in Allerton Drive, Immingham.

Liturgies celebrated in Grimsby and Cleethorpes are live streamed - use this link, or type ‘YouTube Holy Trinity GCI’ into your browser to celebrate with us.
