Work to clear the site of Northampton`s old bus station has been completed ready for potential developers to move in.
Greyfriars-which was built in the 1970s and likened to the mouth of hell by critics-was demolished using explosives in March.
The borough council said it would now be put on the open market.
Councillor Mary Markham, Leader of Northampton Borough Council, said: The Greyfriars site represents a once-in-a-generation opportunity to transform this area of the town centre. We have already had considerable interest in the site but given its importance, we don t intend to rush into anything. We are asking developers to come forward with proposals, which will then be considered in the wider context of what they bring to the town as a whole and how they enhance our existing facilities.
The whole landscape of Northampton is changing very rapidly and we expect to see proposals with vision and ambition for a scheme that matches what we are already achieving elsewhere through the Northampton Alive programme.
