Posty of Praha, Klausová Synagoga ~ Czech Republic

It look like mysterious place from Czech Republic, you know why? First I got with wrong Postcrossing ID, so I can't register (If you are Postcrossing member, you know what I mean by this). It is my first postcard received from this country. Secondly I hardly find any detail of this place written in English. It seems this area is Jewish heritage or Jewish museum located in Prague. It has beautiful stamp for me, with two little turtles on it.

Thanks to Jewish Museum where finally give me correct info of this place, you can see more of it here.
