* College buildings and grounds in Cambridge: This is the most obvious part, encompassing historic buildings, student accommodation, libraries, administrative offices, and extensive gardens.
* Land and farms in the UK: Trinity College owns significant agricultural land, both near Cambridge and further afield.
* Investments and commercial properties: A substantial portion of their wealth is tied up in investments, which likely include commercial properties in various locations.
Therefore, giving a specific number for "how much property" they own is impossible without access to their internal financial records, which are not publicly available. Any attempt to estimate the total value would be highly speculative. The college's overall endowment is much more frequently reported (though still not fully transparent), but that includes things beyond property.
