Councillors have voted to demolish the Futurist theatre in Scarborough.
They voted 22 in favour of demolition, 21 against and one abstained.
Around 200 anti-demolition campaigners marched to the town hall this afternoon.
There was anger outside from protestors who say they still hope to get the building listed to prevent it happening.
The venue on the south bay closed three years ago because the council could not afford to subsidise.
