If you are sloping around Montparnasse looking for a peaceful spot, go no further. This small museum, built around Bourdelle's atelier and adjoining buildings, has beautiful courtyard gardens packed with his sculptures, as well as large exhibition halls with the same, including plaster casts.
Bourdelle was a student of Rodin and there are some influences to be spotted, but mostly his work is massive, muscular, even the women, and substantial. If you like your bronzes this bold, you will enjoy this hugely.
It was encouraging to see students sketching on a sunny day. Oh, and it's free to visit, plus you may be greeted by the smiliest and most welcoming museum staff in Paris.
