Jewish site recs in France?

Weird question but are there any French Jews/Jews who live in France on this subreddit? I’m studying abroad in Paris in the spring and bc I’m a big history nerd I was wondering if anyone had any particular historical Jewish sites they’d recommend taking a visit too (could also be in northern Spain as well). Also if any French Jews have any synagogue recommendations in Paris as well (I’m Orthodox), I’d appreciate it!
