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.

Please click on our “Mass times” page or the weekly bulletin to find what's on, where and when.

Our parish is served by two excellent primary schools – St Mary's Catholic Primary Voluntary Academy, in Wellington Street, Grimsby and St Joseph's Catholic Primary School, a Voluntary Academy in Philip Avenue, Cleethorpes. Have a look at “Our Schools” page for more information.

Please do come along to our churches or St Mary’s Presbytery to say hello!

With my prayers and best wishes for you and your family,

Fr Andrew Cole
