Thank you all for the nice comments.
Greg, the French call that place ´Art´... or hate it. I cannot post another picture here, but you will find plenty of it on the net. It´s basically a huge (microfilm) library (not as big as the national ´Mitterrand´ one) and also serves as a place for interesting exhibitions. I went there to see an impressive Edvard Munch paintings collection; very unexpected for me, it´s not all looking like ´The Scream´.
Sigma DP2x is the little fixed 41mm eq. lens downscaled thingy - 4.7 Mpix, ´x3´ as they say - I really wanted to try out the Foveon look once and took advantage of the one day when the Swiss Frank plunged down to 1 : 1 against the Euro (has been as high as 1.70!), so basically got it at 50% off swiss price...

I do not regret it since to be honest.
