The bullring on the big square
The famous bullring in the Portuguese capital was opened in 1892. The dated building should now be restored completely. To make this plan true the arena had first of all be fully restored and repaired. The sub-humid climate, the nearby Atlantic coast and the air pollution, leaving their traces on the brick facade of the bullring.
"We are very pleased with the result. The facade of the arena shines again."
With great effort to achieve the target
