 The first extramural hall established by Trinity College under the name Trinity Hall was located near Hoggen Green (now College Green), on land which had originally been intended for use as a 'bridewell' or house of correction for vagrants.The land, located to the west of Trinity, was sold to the College by Dublin Corporation for the sum of £30 on condition that it be converted for educational use.A Master was appointed, buildings were constructed, and the site was used for teaching and residence by students from 1617 onwards.
