> Guinness actually doesn’t pay any rent for its iconic St. James’s Gate Brewery in Dublin. That’s because the site has been owned by the Guinness family since 1876, and the current lease runs until 2031.
From 1759 to 1876 is 117 years.
FWIW, as far as I can tell, a 9,000 year lease would have conflicted with the rule against perpetuities. Certainly Cadell v Palmer (1833) set the limit as "lives in being plus twenty-one years[1]" and I gather from https://www.lawreform.ie/_fileupload/Reports/rRuleAgainstPer... that something similar have applied in Ireland at the time of Guinness, certainly by 1833.
As an interesting observation, Arthur Guinness II lived 1768-1855 and 21 years later is 1876. I'm now curious about the actual text of the lease, but I can't easily find a copy online.
