The Winstanley Lecture Theatre is a fully-equipped audio-visual theatre, with seating for up to 150 people.
To reach it, turn into Whewell's Court from Trinity Street. Turn right immediately after the first arch and climb the stone stairs. At the top of the stairs, follow the path round the ziggurat-like Wolfson building, leaving it to your left. Then turn right into Blue Boar Court. The Winstanley Lecture Theatre is on the east side of the Court.
