The London Dungeon and Tower Bridge Experience have joined forces to offer special entry 'after dark' throughout the month of August. Both attractions will be welcoming visitors until last admission at 8pm.

The Bridge and the Dungeon are situated within an easy ten-minute riverside walk of each other. Visit either attraction at any time throughout August and receive a discount voucher for the other valid for use between 6pm and 8pm.

The Tower Bridge Experience is the museum inside the bridge and will be open during the evenings throughout August.

The glass-covered walkways, 45 metres above the Thames, will be open to the public to enjoy spectacular views of London, with an experienced guide on hand to answer questions.

The London Dungeon is the world's first medieval, fully interactive horror museum. Journey back to 1666 to re-live the Great Fire of London in this new-for-2000 feature. And afterwards, stop off at the Dungeon Diner for a bite to eat.
