I am fairly sure that I am named for a Beatles album, though my father denies this upon my asking. Evidence:
My name is Abbey, not Abigail
My dad is a huge Beatles fan
They have an album called Abbey Road.
I don't think it's that much of a stretch, and I thought it would be a travesty not to visit this location once I learned about it.
The assassination of John Lennon: When John Lennon died, it rocked the world (no pun intended). So many people were moved by his passing that monuments and mementos were everywhere. However, this particular spot has managed to stay maintained by the public and his fans from all over the world to this day.
Lennonism and Communism: The Lennon Wall gave birth to a movement of people that fought to express John's ideas, primarily circulating around peace, love, and peaceful activism. This became especially important during Communist Rule in the Czech Republic.
How this demonstrates oppression: The wall was painted over by the government several times in an attempt to stifle public protest.
Climate Change: This past Earth Day, an organization orchestrated a full cover of the wall to spread awareness about climate change and environmental activism. The wall has also been used by organizations to commemorate important historical anniversaries, like that of the Velvet Revolution.
