A lecture on the history of Pārdaugava and an excursion with an insight into antiquity in cooperation with the association "Bolderājas grupa". The oldest part of Bolderāja in the Riga development plan has been marked with a building protection status. The building protection status protects the ancient street network and the historical buildings, which has been formed since the 17th century, after pilots and customs officers started to dwell there permanently. When Bolderāju was annexed to Riga, the names of the streets changed, but some houses continued to be called by the names of their residents for several generations. "Bolderājas grupa" together with its head of association Sandra Jakušonoka takes a deep interest and advocates for the development of the Bolderāja neighborhood. She conducts historical research, leads various excursions and organizes meetings of like-minded people.
