LX Scala 2017 is invading Lisbon

LX Scala 2017 is invading Lisbon

For the second year in a row, we’re thrilled to be hosting LX Scala in Lisbon, Portugal!

On May 12th, in partnership with our friends at e.near and Codacy, we will be bringing Scala professionals from around the globe to the Microsoft Headquarters for an awesome event.

With one-track, eleven speakers, and nine presentations, there will be plenty of Scala knowledge to absorb. But, we don’t expect you to only sit in talks, this conference gives you the opportunity to network with speakers and attendees, toast to accomplishments (seriously, we’ve got special beer for you (and of course, non-alcoholic drinks are available as well), and party away from screens.

LX Scala Beer

There are two events proceeding the conference so you can whet your appetite before the main event:

PTJUG & GDGLX Session on May 9th will be held at the Instituto Superior Técnico and feature two speakers: Miguel Duarte from Equal Experts will present Modern Java with Javaslang and Lombok and our CTO, Raúl Raja, will cover Functional Error Handling. You can find out more and RSVP here.

Then on Thursday, May 11th, the Scala User Group of Portugal will be hosting a meetup with two presentations, pizza, and beer! Jorge Agudo from ThoughtWorks will be presenting (DYS)Functional Programming with Scala and Nuno Marques from Equal Experts will present Discovering FP Design Patterns in Scala.

But don’t get too crazy, you need to rest up for the main event on Friday!

The Closing Party

After a full day of ingesting all things Scala, head over to the closing party to ingest some delicious food and drinks and enjoy music and lively conversation. We’ve chosen Time Out Market Lisboa because of it’s rich offerings of traditional Portuguese food and drinks. It’s also listed as one of the top things to do in Lisbon!

You have time to grab dinner before the party, and we recommend doing so at the Market which includes satellite stalls from some of the country’s top chefs. Then, after you’ve had your fill of exploring, head up to our private party overlooking the bustling market where we’ll have drinks, music, and general revelry.

Making a vacation of it?

Lisbon is one of the top destinations in the world and is known for its beauty, delectable eats, and diverse culture. If you’re looking for places to eat, things to do, sights to see, here are a few recommendations from Jorge Galindo:


As if Lisbon’s picturesque streets weren’t seductive enough, they often lead to the top of hills that force contemplation through terraces serving as viewpoints. It is here that you’ll conclude that Lisbon is indeed one of the world’s most beatiful cities. Check out:

Put away your map and wander aimlessly through the “becos” (alleys) and “largos” (small squares), allowing your senses to be your guide. You’ll see laundry out to dry from balconies and magnificent views of the river, smell fish being grilled in a corner, and hear the sounds of Fado coming out of a restaurant. Visit S. Geourge’s Castle, located on the city’s tallest hill, offering a breathtaking view over Lisbon. It was first built in the 6th century and was occupied by the Romans and Visigoths before it became a Moorish royal residence.

Bairro Alto

At the end of the day, Lisbon comes out to party on the streets of Bairro Alto. It starts with late night dining and bar-hopping and leads to an impromptu street party of locals and tourists of all different backgrounds conversing and drinking into the wee hours of the morning.


Lisbon’s most elegant and trendy neighborhood is where everyone meets for coffee, shopping, or before dinner and a night out in neighboring Bairro Alto. Try:

Other Interesting Places:

Belem: It is known as the historical district of the Age of Discovery. It was from this riverfront that Vasco da Gama and other explores departed for their voyages; events celebrated today by grand monuments and museums in the neighborhood.

Vintage Rides: The antique trams that cross Lisbon’s narrow streets are truly a trip back in time, but vintage rides are the iconic funiculars that climb the steep hill, offering a charming “only in Lisbon” experience. You must go on Tram 28.

Portuguese food:

Some our favorites places to indulge in good Portuguese food:

  • The Decadente: Hostel restaurant / very cool and good food and drinks. Rua de Sao Pedro de Alcantara 81 (Barrio Alto)
  • Chapito Restaurant: Has also a great terrace for beer and snacks. Costa do Castelo,7. Alfama
  • Mercado da Ribeira: Trendy food quarter with all kinds of restaurants. Praca D. Luis I
  • Bistro 100 Maneiras: Charming restaurant. Largo da Trindade 9

We hope you enjoy Lisbon and after you get your fill, if you want to explore more unique cities in Portugal, consider attending our sister conference, ScalaSwarm, in Porto in June!
