To see Simancas – Nice castle

“Interesting castle by the road. I must get time to stop and visit.”

How many times did that thought come to my mind?

​Which means “How many times have I passed there”?

However, reading something about it, I discovered that I should stop and enter, as the AI explains to me:

“The castle was used as a prison in the Middle Ages and during the 18th and 19th centuries, earning it the nickname “Castle of Books” due to the large number of historical and literary documents that were kept there. Currently, it houses the General Archive of Simancas, one of the most important archives in Spain, which contains a large number of historical and administrative documents related to the Spanish monarchy from the 15th to the 19th centuries.”
