According to the government press release:
 

Cemetery caretaker Viktor Nagy said that the first Jewish families settled in Rácalmás in the 1720s and the cemetery was opened in 1740. Research into local history has confirmed the existence of a thriving Jewish community, he said, adding that some 300 people from Rácalmás had fallen victim to the Holocaust.

Mr. Nagy also mentioned that renovation work had been ongoing since 2013 in cooperation with the Federation of Hungarian Jewish Communities (Mazsihisz) and with the help of over 20 volunteers. The restoration of the lower part of the 1300 square metre cemetery has been successfully completed, and work will continue in the upper area in the autumn.
