Recently, the school has gone through a long period of searching for a building big enough to house all students.
Before 2006, the school was located in two buildings on the Oudegracht, at walking distance called the Diac and the PAS.
The school even had a third location in the academic year 2005–2006 on the campus of University College Utrecht.
The PAS has now been closed and the University College-location couldn't be maintained in academic year 2006–2007.
The anthem of the Christelijk Gymnasium Utrecht was penned by Dr. Dolf Peeters and was created in 1946/47 to commemorate the school's 50th anniversary.
