La Place de Rémy opened in Walt Disney Studios Park, Disneyland Paris in summer 2014 and features the hugely popular 4D trackless attraction, Ratatouille: The Adventure. The ride's exit takes you past Bistrot Chez Rémy which, of course, serves ratatouille!
"it's a small world" was originally created for the UNICEF pavilion at the 1964 New York World's Fair and opened at Disneyland in 1966. For a history of the attraction, check out FreshBaked's video "Disneyland Secrets and History of it's a small world".
Disney Stars on Parade debuted at Disneyland Paris in March 2017 as part of the park's 25 anniversary celebrations. Unlike its predecessor, Disney Magic on Parade, it consists of all new flats to the resort. There are some familiar faces, however - the Lion King and Peter Pan floats were recycled from Tokyo Disneyland's "Jubilation" parade, together with a replica of the hugely popular Maleficent fire-breathing dragon from Walt Disney World.
Pirates of the Caribbean opened in Disneyland in 1967 and was the last attraction to be overseen by Walt Disney, although he sadly died before it opened. Versions of the ride can now also be found at the Magic Kingdom, Tokyo Disneyland and Disneyland Paris. The attraction has seen numerous changes over the decades, most notably the introduction of characters from the Pirates of the Caribbean films and the 2018 update transforming the popular red head in the auction scene into a pirate.
For a detailed history of the original attraction, check out David O'Neal's feature length documentary. I also recommend FreshBaked's "Secrets and History of Pirates of the Caribbean" and Park History's "The Differences between Disney's Pirates of the Caribbean".
Galaxy's Edge is due to open at Disneyland in the summer of 2019 but in the meantime, an assortment of props and costumes can be found at the Launch Bay in Tomorrowland, alongside character meet and greets.
