 Other benefactions in the 17th century include Herbert Westfaling , the Bishop of Hereford , left enough property to support two fellowships and scholarships ( with the significant proviso that " my kindred shallbe always preferred before anie others " ) . Sir Eubule Thelwall ( principal 1621 – 30 ) spent much of his own money on the construction of a chapel , hall and library for the college . The library , constructed above an over @-@ weak colonnade , was pulled down under the principalship of Francis Mansell ( 1630 – 49 ) , who also built two staircases of residential accommodation to attract the sons of Welsh gentry families to the College .
