Nerudova street in Prague - one of the most iconic streets in the city - amongst others of-course - going from Malostranska square to the Prague Castle.
You can go up , or you can descend from the Castle towards the Lesser and Old Town of Prague (Charles Bridge maybe ...).
Why is it interesting - well the beautiful baroques style buildings - those today are home to embassies, hotels, cafés, restaurants, shops , you name it... the name of the street is taken from Jan Neruda, famous Czech writer and journalist (the house he lived in has a bas-relief at the upper level and 2 suns on the front) who lived on this street.
If you are not into architecture , but looking for some souvenirs or a place to have a drink or grab some food, on this street you may find some very good choices, don't forget to put this street on your itinerary when visiting Prague.
