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.

Where was the chapel built? Choose the correct option.

In the garden of love

The correct answer is In the garden of love.

The poem clearly states that the speaker used to play on the green "where" the chapel was later built. This indicates that the chapel was constructed within the Garden of Love itself, transforming its nature from a space of play and joy to one of restriction and death.
