Which of the following is closer to the actual function of the Tower of London?

The actual role of the Tower of London is now as a tourist attraction. But it also served as a fortress, an armory, a palace, an execution ground, a public records office, an observatory, and even a prison for upper-class prisoners. The Tower of London was last used as a prison during World War II for Rudolf Hess.

The World Cultural Heritage Tower of London (English: Tower of London) is a palace and castle located in the center of London. Its official name is "Her Majesty's Palace and Castle, Tower of London", so although it is regarded as a palace The last ruler to live in it was James I (1566-1625) centuries ago, but it is still nominally a British royal palace.

The Tower of London served as a fortress, armory, treasury, mint, palace, execution ground, public record office, observatory, asylum and prison, especially for prisoners of the upper class. This last use gave rise to the phrase "sent to the Tower," meaning "to go to jail." Elizabeth I was imprisoned here for a time during the reign of her sister Mary I. It was listed as a world cultural heritage in 1988.

Now the Tower of London is mainly a tourist attraction. In addition to the building itself, you can also see the Crown Jewels of Britain, some exquisite collections of the royal armory, and a remaining section of the Roman fortress wall.
