Cambridge University students enjoyed a fireworks display and a night of partying at the annual Trinity May Ball to celebrate the end of their exams.
The first Trinity May Ball was held in 1866 and the tradition quickly spread to other colleges.
Despite now taking place in June they are still called the May Balls, as that is when they were originally held.
The event is described on its website as 鈥渙ne of the most sought after tickets to be had in May Week鈥 and 鈥渁n unrivalled showcase of revelry鈥.
Entertainment ranges 鈥渇rom chart-topping stars to world-class comedians to the finest classical and jazz musicians鈥 in an 鈥渦nparalleled setting鈥.
In years gone by, some of Britain鈥檚 brightest students have engaged in hedonistic behaviour, stripping off and jumping in the river.
The ball has been held every year since 1866, apart from 1910, when King Edward VII died, during the Second World War between 1939 and 1945, and in 2020 and 2021 because of the Covid-19 pandemic.
The 鈥渙nly acceptable attire鈥 for the Trinity May Ball 鈥渋s traditional black tie, white tie or formal national dress鈥.
Instructions on what to wear include that 鈥渁ny sword worn as a part of national dress must be fixed in its sheath鈥.
Organisers said that the dress code 鈥渨ill be strictly enforced; those who are not properly attired will not be allowed entry into the ball鈥.
