Wren. Nevile's building campaign drove the college into debt from which it surfaced only in the 1640s, and the Mastership of Richard Bentley adversely affected applications and finances. Bentley himself was notorious for the construction of a hugely expensive staircase in the Master's Lodge, and for his repeated refusals to step down despite pleas from the Fellows. Modern day In the 20th century, Trinity College, St John's College and King's College were for decades the main recruiting grounds for the Cambridge Apostles, an elite, intellectual secret society. In 2011, the John Templeton Foundation awarded Trinity College's Master, the astrophysicist Martin Rees, its controversial million-pound Templeton Prize, for "affirming life's spiritual dimension". Trinity is the richest Oxbridge college with a landholding alone worth £800 million. For comparison, the second richest college in Cambridge (St. John's) has estimated assets of around £780 million, and the richest college in Oxford (St. John's) has about £600 million. In 2005, Trinity's annual rental income from its properties was reported to be in excess of £20 million. The college owns: 3400 acres (14 km2) housing facilities at the Port of Felixstowe, Britain's busiest container port the Cambridge Science Park the O2 Arena in London (formerly the Millennium Dome) In 2018, Trinity revealed that it had investments totalling £9.1M in companies involved in oil and gas production, exploration and refinement. These included holdings of £1.2M in Royal Dutch Shell, £1.7M in Exxon Mobil and £1M in Chevron. On 17 February 2020, protestors from the campaign group Extinction Rebellion dug up the front lawn of Trinity College to protest against the College's investments in fossil fuels and its negotiations to sell off a farm in Suffolk that was to be turned into a lorry park. In 2019, Trinity confirmed its plan to withdraw from the Universities Superannuation Scheme (USS), the main pre-1992 UK University pension provider. In response, more than 500 Cambridge academics signed an open letter undertaking to "refuse to supervise Trinity students or to engage in other discretionary work in support of Trinity’s teaching and research activities". Legends Lord Byron purportedly kept a pet bear whilst living in the college. A second legend is that it is possible to walk from Cambridge to Oxford on land solely owned by Trinity. Several varieties of this legend exist – others refer to the combined land of Trinity College, Cambridge and Trinity College, Oxford, of Trinity College, Cambridge and
