Katarína from Prague

About me I see the world through visuals. Studying art history and then "taking photos" with words as a magazine editor has been a dream come true. My passion lies in interior design, architecture, unconventional spaces, and the beauty of everyday life. I used to go to many local travel festivals and talks with amazing travellers. I was lucky to edit a travel book for one of them. ...

Větráky Letenského Tunelu Prague

Timeless creativity

"The four ventilation chimneys above "Větráky Letenského Tunelu" are covered in abstract digital mosaics developed all the way back in 1969!"

Art is all around you in Prague. Its integration into everyday life can be so clever that you can pass by and overlook an important artwork without knowing. The four ventilation chimneys of Letná road tunnel (Větráky Letenského tunelu) in the city park Letenský sady are a remarkable example.

I am so proud to know about this monumental artwork that has no competitor. The four 20-meter chimneys are covered with black and white mosaics. It is hard to believe that you are looking at art co-created in 1969 by using a computer for creating abstract geometric paintings. The modern expression and revolutionary technique, for the period, deserve admiration.

There are just a few people outside professional circles that know about this most spectacular work of well-known Czech painter Zdeněk Sýkora (1920-2011). The chimneys are situated near the entrance path to the city park. Anonymously, without any description. I discovered more information about them in an exhibition. I remember my surprise like it was yesterday. Since then, I have paid a lot of attention to them.

A taste of France by the river

"Na Břehu Rhôny" is for sure my top choice when it comes to wineries in Prague. Here you form a personal relationship with the wines. Oh, and the quiche!

"Libeňské Doky" is a new district of posh residences (with private marinas!) in Prague. I love walking or riding my bike along the trail next to the water.
