The Technical Museum of Slovenia in 2012 succeeded in obtaining funding from the Ministry of Education, Science, Culture and Sport for the returning of the original statues of Neptune fountain to the Polhov Gradec mansion. Statues were restored by the Restoration Centre of the Institute for Protection of Cultural Heritage of Slovenia. The opening of the new exhibtion was on 7th December 2012.
The Neptune fountain, in the courtyard of Polhov Gradec mansion, is one of the most interesting cultural monuments in 17th Slovenian century, because of its unique shape. A rectangular pool is surrounded by four corner pillars, richly decorated with plant ornamentation, on which four nymphs are placed. The central character, the mythological deity Neptune, is rising on the central pillar.
