British Library, London

Designed by Sir Colin St John Wilson and unveiled in 1997 following nearly two decades of construction, this Grade I listed red-brick edifice was once a subject of controversy. It now serves as the custodian of the national collection of books, manuscripts, and maps. Collectively, the British Library boasts an astounding 170 million items spread across its locations in London and Yorkshire, encompassing approximately 14 million books. Access to these treasures is available to individuals possessing a Reader Pass, which can be pre-registered for online.

However, the true gem lies in the "Treasures of the British Library" exhibition. Here, visitors can marvel at remarkable artifacts, including the Magna Carta, the Codex Sinaiticus (an ancient Bible containing the oldest complete copy of the New Testament), Shakespeare's First Folio, Jane Austen's writing desk, and lyrics penned by the Beatles (including John Lennon's hand-written lyrics for "In My Life", "Strawberry Fields Forever", and "She Said She Said", along with Paul McCartney's draft on "Yesterday").

The library also hosts other rotating free exhibitions, although these often have earlier closing times than the main building during weekdays. Attendees can also partake in talks, discussions, and workshops. Throughout the year, the library organizes outstanding special exhibitions, usually requiring an admission fee. It's highly advisable to take one of their tours, which encompass a visit to the Viewing Gallery; booking at least two weeks in advance is recommended.
