In 1606, the Company bought Abergavenny House in Ave Maria Lane and moved out of Peter's College. The new hall burnt down in the Great Fire of 1666 along with books to the value of about £40,000. It was rebuilt and its present interior is much as it was when it reopened in 1673. The Court Room was added in 1748 and in 1800 the external façade was remodelled to its present form.
