Bonjour G,

Thank you for pointing this out! We have amended the text to include both options (with the capital letter and without), i.e le Pont de... / le pont de... / la tour Eiffel / la Tour Eiffel.

The grammar rule is as follows: le pont de + Noun /  la tour + Noun according to l'Académie française. However, in it is very common to come across the capitalization of the first word. Therefore we have accepted both options.

I hope this is helpful.

Bonne journée !
