Here is a list of sims I enjoy visiting from time to time. I apologize if any landmarks become out of date, as I know some sims poof at times.
Paris in the 1900s – A reconstruction of the real life Paris, France during the 1900s with some of the most iconic landmarks of the City of Love, including the Eiffel Tower, the Arc de Triomphe, the Moulin Rouge, and the catacombs.
Mirrormere – A collection of beautiful sims with varying landscaping.
{Serenity City} – This sim has a few of my favorite shops, including =EC Designs= and Mishmash Fusion, as well as a ballroom, a bar, racing track, and more to explore!
Maison de l’amitie – Photoesque sim that changes every few months
