You are really bad Ann... poor John! :)
Poble Espanyol, for those not in the known, is a tourist attraction in Barcelona, in the slope of Montjuïc mountain, off Plaça Espanya, which was designed for the Barcelona International Exhibition of 1929 as a synthesis of Spanish architecture, handicrafts and cultural wealth of the nations of Spain to show the international visitors. It consists of a series of life-size reproductions (over 100 of them) of different architectural styles in different parts of Spain. Thus, one has a typical "caserio" from Galicia next to a "cortijo" from Andalusia or a "palacete" from Castilla etc. One can walk thru narrow streets as if visiting a village featuring these reproductions but very few can be visited inside. Also, many artisans established themselves in this complex, offering products ranging from glass figurines to handmade Spanish guitars to jewellery among other. Many artisans have their workshops onsite and some offer the possibility to see them "at work" while creating their products. The site features a few "plazas" (squares) which offer concerts from time to time, especially during the summer months, and it's full of restaurants and terraces. There are also some open air clubs with DJs that boost the top charts in summer nights until the wee hours. They also host different festivals through the year, like a medieval fair, a giants contest (https://ca.wikipedia.org/wiki/Gegant_(folklore)), a Castellers' event, an outdoor sing-along day, etc.
It's visited by many tourists, 1.3 million in 2016.
This is the latest presentation video of the complex, however, to be closer to what you'll find if you decide to go, add a gazillion visitors to the place: https://www.youtube.com/watch?time_continue=2&v=ORuvg4smLLg
No, it doesn't feature any Modernist example by Gaudi or any other Modernista architect.
Now -- and this is just "my personal view"!!!-- if you like Disneyworld-like places full of fake cardboard sets, chaotically mixing styles of different ages and places with no sense whatsoever, surrounded by expensive shops and restaurants selling crap at high prices and being constantly rushed by a mob of visitors... then, by all means, do visit Poble Espanyol. Otherwise, if you are looking for authenticity, if you value a minimum level of quality while having a snack or a lunch and if you're looking for a souvenir to take back that does represent a bit the place and culture you've been visiting ... stay away.
