On his retirement at the end of 2008, the post was filled by Chris Hayes, the former principal at St Edmund's, Canberra. Some buildings on the Senior Campus, and Studley House at the Burke Hall Campus, are listed on the Victorian Heritage Register. Xavier has a long-standing rivalry with St Kevin's College, in legal circles, an Old Xaverian Supreme Court judge quipping that 'You boys who were taught by the Brothers can never aspire to the Supreme Court. Positions on that Bench are reserved for those of us who were taught by the Jesuits'. Memorial Chapel An Italian Renaissance style chapel was built in 1927 to celebrate the golden jubilee of Xavier College. From conception to completion, construction took around sixteen years and was led by Rectors Edmund Frost and Frank O’Keefe. The foundation stone reads: Burke Hall In 1920, Studley Hall, a gift from T.M. Burke, a Catholic businessman, was opened in 1921 as Xavier's first preparatory school. James O'Dwyer SJ, Rector of Xavier between 1908 and 1917, became Burke Hall's first headmaster, before the campus was renamed Burke Hall several years later in honour of its benefactor. Burke donated a classroom block in 1923 and, in 1926, Burke's wife provided funding for a construction of a chapel in memory of her deceased brother. The campus was extended in 1966 with the donation of an adjacent mansion from the estate of John Wren following his death. After renovations to the original ballroom, which in 1975 became the library, and the original hall had been converted to classrooms, a new classroom block was built in 1987. A multi-purpose hall was constructed in 1997 overlooking the main oval that was re-graded in 1998. In 2002, a co-educational Early Years Centre was opened on the Burke Hall campus for students up to grade 4. In 2011, a new classroom block, the St Mary MacKillop Building, was added and named after the first Australian-born saint, the St Mary MacKillop is a space for classes year 5 & 6. Kostka Hall Following the request by Daniel Mannix, Archbishop of Melbourne, that the school should have a campus in the southern suburbs of the city, William Hackett SJ, Rector of Xavier opened the Kostka Hall Junior campus in 1937, with the addition of a second building, Marchwood (also known as St Johns). This was demolished in 1959 to make way for a major building project,
