As work progresses on the Guardians of the Galaxy roller coaster, Disney has now installed walls around the Universe of Energy pavilion.

A look over the walls from the monorail shows that no exterior work has been done yet.

A look at the northwest side of the building. Work is ongoing in the interior of the building and a plot of land has been cleared to the northeast, but no exterior work is visible just yet.

The Guardians of the Galaxy roller coaster will officially open by 2021.
