The Eiffel Tower was a DLC released in celebration of Bastille day. It is the Eiffel tower, and is able to lite up when touched. It works just like a light, but looks like a model of the Eifell Tower. It's a piece of furniture that sells at Tom Nook's for 3,600 bells.
This piece of furniture is a replica of the actual eiffel tower in france. In this game, it works just like a light, and resembles the model figures that Tom Nook gives you when reaching a certain status on his point system.
The letter received for the Eiffel Tower in Europe read: Dear [Player], In France we celebrate Bastille Day on 14 July. Will you celebrate with us? This model tower will shine a light on any party! From the French staff
