Wren Library

Remarkable visit if you can make it. Only opens for a couple of hours during weekdays for visitors. Aside from the incredible interior (no photos though), displays include a manuscript of Winnie the Pooh by A. A. Milne, some of Newton's possessions like his walking stick and even a lock of his hair!

Although the library is small and linear, it is unique, spacious and has remarkable architecture. This is certainly a must visit, although do note that the rules are strict: no more than fifteen visitors at a time, absolute silence required and no photos allowed.

Famous library, open to public visits as well. It houses many valuable books and manuscripts, many of which are for on-site reading only.

The Wren Library, library of Trinity College in Cambridge. It was designed by Christopher Wren in 1676 and completed in 1695. The library is a single large room built over an open colonnade on the ground floor of Nevile's Court. It's credited as being one of the first libraries to be built with large windows to give comfortable light levels to aid readers.

Worth going inside when it's open to see rare artifacts from literature, science, and more.

We very luckily had the place to ourselves for the first half of our visit (it's always a good idea to get to these attractions mega early). The space itself is stunning, both inside and out. There are various items of interest to see in display cases, such as Newton's walking stick and the original copy of A.A. Milne's Winnie the Pooh.
They are very strict on not taking photos and I'm not entirely sure why. They ask all phones to be switched off which I get, but I'm not sure if the no photo rule is to do with security or potential damage to the old manuscripts. Either way it's a shame as the place is begging to be photographed.

The man running the visitor desk is extremely rude. Get there early and hope he's pleasant with you.

Visiting hours are quite limited, but it's free entrance. Inside you'll see beautiful library build by Wren, with some unique and old books on display. Must have visit if you're walking around the colleges, but do check visiting timetable in advance
