When is a mass in the church? Is it open to all? On all Sundays there is mass 11 am and on Wednesdays 8 am. They are open to all and the Eucharist as well. These services are in Icelandic but the pastors quite often summarize the sermon in English when there are some foreigners in the crowd. English service on the last Sunday in every month 2 pm. Hallgrimskirkja is a wonderful place to worship. No wonder the Guardian has picked the church as one of ten best houses for reflection in the world. And you are welcome – all the best in the world is free!
