The photo reminds me of a Bible verse, as explained by my nun teachers, how a rich man has too many treasures and can not pass the narrow passage, but a poor man has little and can squeeze through. Also information is now on the Internet, see source link at bottom of post. It seems the nuns were correct.
“And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven.”
The eye of the needle used to be in Damascus and was a side gate alongside the main gate of the “street called straight” Being a side gate it was not intended for passage by animals, especially camels carrying side loads. So it was nigh impossible for the act to happen.
