 Since its construction, the tomb has become a place of veneration for Marx's followers, including some, such as the anti-apartheid activist Yusuf Dadoo and the founder of the Notting Hill Carnival Claudia Jones, who have been buried nearby.The tomb is maintained by the Friends of Highgate Cemetery Trust, a charity which acquired ownership of the cemetery in 1975.The trust's policy of charging an entrance fee to the cemetery, to cover the costs of upkeep and maintenance, has generated some controversy.
