At the west end of this bridge , a four @-@ inch equatorial was installed on semicircular bastion . The east end of the bridge , above the barracks of the gendarmes , had a heliograph , with a camera attached , used to photograph the Sun ( photoheliograph ) . A new 16 @-@ inch visual telescope , called Torre Pio X , was erected in the second tower . As a result of these modifications , the original library was moved to the Pontifical Academy Lincei , and the old meteorological and seismic instruments were shifted to the Valle di Pompei observatory . The new Astronomical Library was housed in two rooms of the building . The two new Repsold machines were used for recording on the astrographic plates .
