During the constitutional convention discussions the doors to the building were shut.

Explanation:

On Tuesday, May 29, 1787, with the arrival of John Dickinson of Delaware and Elbridge Gerry of Massachusetts, there was the necessary seven-state quorum in the State House and the real work of revising the Articles of Confederation could begin. The body was called upon to consider the secrecy rule proposed prior to the arrival of Dickinson and Gerry.

The secrecy provision mandated "That no copy be taken of any entry on the journal during the sitting of the House, without leave of the House. That nothing spoken in the House be printed, or otherwise published or communicated without leave."
