Business hours at the Royal Exchange only took up a small part of the day. The rest of the time, the space lay open to other uses. As this Hollar engraving illustrates, commercial space could slide into recreational space out of hours: here you can see children at play, and ladies and gentlemen strolling in pairs under the colonnade.
