Catering package

Catering is provided by the Kitchen Crew at Calafou for the full day including breakfast, lunch & dinner. Vegan, vegetarian and carnivore options available.

This catering option is optional but recommended. Calafou is located outside major urban areas which means restaurants / bars are limited.

Catering package price

Catering cost is 18 EUR per day and there is a 6 day pack discount which reduces the cost to 15 EUR per day (total: 90 EUR).

Paying for the food is only possible in cash and during the event

Catering package service introduction

The calafou collective kitchen service is a catering project for calafou events that aims to generate networking and dynamism for the community while providing a source of income and sustainable working conditions for the people who work there. We want to offer and facilitate the cooking service for the participants with a political objective of promoting food sovereignty in the territory, with local suppliers and related alternative projects, while offering healthy meals at affordable prices. Where possible, we incorporate fair trade, km0, organic and seasonal products. We want to introduce the vegetarian and vegan diet in greater proportion to choose more ethical and responsible interspecies options.

We are starting the project and we are excited to offer Battlemesh a kitchen suitable to the demands and possibilities. For this reason, we have a proposal with seasonal products from the local organic garden, vegetables, and recycled organic natursoy products, among others. One of the daily meals will be exclusively vegan and the rest will be vegetarian based with omnivorous options. We guarantee the vegan diet, gluten-free and other possible allergies to people who require it. Along these lines, we also want to offer options for refreshments and drinks during the event in the same political line, with beers from the Calafou cooperative Subversiva coop, as well as from other alternative producers such as altercola. We hope you enjoy the experience!

Catering package timetable

• lunch time: 14:00 - 15:00

Catering package menu

Basic information to be in Calafou

Please take a look in the official calafou's wiki about the basic information when you are in Calafou https://wiki.calafou.org/index.php/INFO_B%C3%81SICA#English

How to get there

You can find instructions below or on Calafou's wiki here:

https://wiki.calafou.org/index.php/INFO_B%C3%81SICA#How_to_get_there

By train

The basic steps are:

1. get to Plaça d'Espanya square;
2. enter "Barcelona - Pl. Espanya" FGC train station;
3. buy the ticket and take the right train and get off at "Vallbona d'Anoia" stop;
4. walk to Calafou.

In detail:

1. get to Plaça d'Espanya square

* from the Barcelona El Prat airport: follow the indications for the Aerobus (6.75€ one way, 11.65€ return. The return ticket is valid for 90 days). In case you prefer a cheaper option, refer to the Calafou wiki accessible here: https://wiki.calafou.org/index.php/INFO_B%C3%81SICA#How_to_get_there Once you are in Plaça d'Espanya square, look for the underground FGC (ferrocarril) station (ferrocarril is a kind of local train, but it is not the most common one). You should see the FGC logo like this: https://www.fgc.cat/wp-content/uploads/2020/06/logo-FGC-square.png

* from the metro network: get to "Espanya" metro station, it is reachable with the metro lines L1 (red) and L3 (green). Once you get off from the metro, you need to follow the indication for the FGC (ferrocarril) trains (ferrocarril is a kind of local train, but it is not the most common one). You will see this green FGC logo: https://www.fgc.cat/wp-content/uploads/2020/06/logo-FGC-square.png The two stations are underground and connected, but they are physically separated and each one has its own ticket to be bought.

3. buy the ticket and take the right train and get off at "Vallbona d'Anoia" stop

Once you get to the FGC (ferrocarril) station, go to the ticket vending machines and click:

• language
• FGC single ticket
• 1 journey
• other FGC destinations
• go down until finding "Vallbona"

The price is 7.35€

Both (and only) R6 and R60 trains will take you to Vallbona d'Anoia.

The journey should take 80 min approx, as you can see on the time table https://www.fgc.cat/wp-content/uploads/2020/10/R6_Igualada_LA_octubre_20.pdf

4. walk to Calafou:

See the map here IMAGE or follow this walking route on OpenStreetMaps: https://www.openstreetmap.org/directions?engine=graphhopper_car&route=41.52011%2C1.70947%3B41.51159%2C1.70357#map=16/41.5153/1.7068 If you don't want to get to Calafou walking (20 min downhill) you can try to get someone to come from Calafou with a car.

Going back:

You can buy the FGC ticket inside the train station building and you should obliterate it there (try with the yellow slot at the center of a black rectangle on the wall next to the ticket vending machine). In the Vallbona d'Anoia train station there are two train tracks, but the trains in both directions just use the same track: the one closer to the train station building.

About the Battlemesh V15 logo

This year's logo shows a traditional Catalonian "human tower" or Castell. The enxaneta (person on top) carries on their shoulders a large microwave dish which you have seen in previous Battlemesh logos.

What do castells mean *nowadays* in popular culture?

Men-only castells were a declining tradition only a few decades ago. As soon as inclusive colles castelleres (i.e., teams of castellers) appeared in the late 1980s, the castells tradition flourished again and became an open, welcoming, family-friendly, intergenerational activity.

This meant not only more fun, but also better castells. I think Catalan society learnt a valuable lesson from that.

As you may imagine, the higher the castell goes, the bigger and sounder the base (i.e., the pinya) needs to be. This requires lots of people supporting the tower from the bottom. Even in the most signified castells competitions, which occur regularly, it is *common practice* that members from one colla castellera (and also friends, family, supporters, etc.) help a competing colla castellera to fer pinya [1], so that all the castells that are build during the event become more solid and robust.

Isn't it the whole purpose of putting the protocols at test during the Battlemesh, to make them more solid and robust through collaboration of all participants?
