This is the home of Mobile World Congress, the Fira Gran Via. Inside these walls is a wireless wonderland of phones, VR headsets and almost everything in between.
Stare at that fountain and think peaceful thoughts. You have a busy day ahead.
Enter through the revolving doors, but only if you have your badge.
As you enter you have to show your attendee badge several and times and present a photo ID. Security was tight, but friendly and efficient.
You also to have scan your badge in a reader to finally get in. Even with thousands of attendees streaming in each morning, the queues were short.
Once inside you're in a large entry hall. Go up the escalators to access the walkway that stretches across the entire complex or head straight into the mayhem.
Those who've been to MWC before know the fastest way to get across the complex is to go upstairs.
Moving walkways, or travelators, as the Brits call them, take you over the show floor saving you from fighting the crowds browsing exhibits.
Between each hall, escalators take you down to the show floor.
Saving that time is important, as this is a big place. The eight halls spread across 240,000 square meters of floor space.
Lost? Though the venue is well-signed and organized, I wouldn't blame you if lose track of your location. Touchscreen maps help you find your way.
The press room, which is on the upper level, is the domain of media only. If you're covering the show's happenings, you'll spend a lot of time there.
That is, if you can find a seat.
Or you could just set up your work area right outside.
At such a long sprawling show you'll see plenty of people taking a breather anywhere they can.
Fortunately, there are places to catch natural light, including several sunny courtyards.
The courtyards are a nice place to get some fresh air and enjoy a drink or snack.
One is the Android Garden, which carries the theme as far as it can. There's even an Android topiary.
You can even sit outside and watch one of the keynotes.
There are plenty of places to eat in the Fira, serving all kinds of cuisine. This food court of sorts has Mediterranean, Asian, South American and Middle Eastern food stations. It's filling, but not fantastic.
Staring at a screen, either a laptop or your phone, is a common sight.
All that mobile work will eat your battery. But have no fear, as there are plenty of places to charge up.
At the end of the day, the flow of attendees runs the other way. That guy on the left? That's known as "trade show face."
If you're heading to the metro, head up and over the bridge.
As you head out there are still sights to see, like a mime in VR.
I'm not sure what's happening here.
Even with the metro and bus strike this week, transit in Barcelona was relatively smooth. Waiting for a train was usually faster than waiting for a taxi.
