What was written on the door? Choose the correct option.

I went to the Garden of Love,
And saw what I never had seen:
A chapel was built in the midst,
Where I used to play on the green.

And the gates of this Chapel were shut,
And "Thou shalt not" writ over the door;
So I turn'd to the Garden of Love,
That so many sweet flowers bore,

And I saw it was filled with graves,
And tomb-stones where flowers should be:
And Priests in black gowns were walking their rounds,
And binding with briars my joys and desires.
