Shakespeare's A Midsummer's Night Dream opens and closes in the city of Athens, Greece in the mortal world of Theseus' palace. Athens is a non-magical setting as compared to the Woods.
Most of the play takes place in the magical world of the Woods, including the middle three acts of the play. This magical world includes fairies and sprites. It is a place where people drink flower juice, where fantasy is reality. Falling in and out of love is natural in the Woods but ultimately it is a world of harmony.
The final setting is Quince's house, which is also in Athens but is the opposite of the palace in which Theseus lives. This setting is also in the mortal world of the lower class, and the commoners. This is where rehearsals take place since Quince is a carpenter who directs the mini-play about Pyramus and Thisbe.
