Looks like mammoth Russian sunflowers to me. We grow these every year along my driveway and the neighbors love them because they attract gold finches and red-headed house finches :-)

Biblically accurate sunflower.

Those are pretty common in Amsterdam. Both in public spaces and even street gardens

Those look like good old “mammoth” sunflowers. I tried to grow 16 sunflowers this season from different varieties, and only 6 of those survived. They all became monsters.
