A Walk Through Post-Industrial Holešovice
Stop here for a second.
I assume you are not familiar with what the courtyards look like in Prague. Here is a great opportunity to take a look. However, if you're doing this tour at night, the courtyard will be closed. If that's the case, just keep walking straight along the road while I tell you about it.
On your left is a huge red building. Next to it is a section with a very low roof. In that section there's an iron door with a pointed arch above it. Go through that door and into the courtyard on the other side.
The big building has a gymnasium, a restaurant and a martial arts club. This area in the back is a public playground. Places like these used to be neglected. People kept their rubbish and bulky waste here, or it was used as a parking lot. Increasingly, these places have been revitalized, and gardens have been planted and maintained. Many cafés and restaurants have gardens in the backyard.
When you're ready, return to the street. Then continue walking in the same direction as before. I'll catch up with you at the end of the next block.
