Our Lord at the attic Amsterdam

the original interior of the hidden church our lord at the attic amsterdam with altar our lord at the attic amsterdam

After the Reformation Amsterdam churches had to transform from Catholic to Protestant.
Those who had kept the Catholic faith had to go to hidden churches to attend mass. One of the best kept examples is the hidden church ‘Our Lord at the attic Amsterdam’, located in the middle of the Red Light District.
It’s 17th century interior is still intact and very worth a visit.
