Two visitors in front of Boerhaavelaan 6.We have just experienced the Open Monumentendag (Open Monuments weekend; 13-14 September 2025) at the TRC’s new home, Boerhaavelaan 6 (known as B6 at the TRC), here in Leiden, just behind the railway station.The building has recently been acquired by the Stichting Monumenten Bezit, which will shortly, also thanks to Leiden Council, make it available to the TRC.
It was the first time this historic building had been open to the public and we were involved in such an event. It was a steep learning curve, but great fun, both for us and for the volunteers and organisers of the Monumentendag.
The new TRC home, view from the garden.On Saturday B6 was open from 12.00 until 17.00 and on Sunday from 10.00 until 17.00. On both days there was a constant flow of people, much to the amazement and delight of all of us. On Saturday afternoon there were 313 visitors, while Sunday saw well over 650 (I have yet to receive the exact number).
This means that, in total, nearly 1000 people came to see the villa. There were guided tours with a brief introduction being given of its intriguing history, or people could simply wander around the house. As somebody said, the history of the 20th century is encapsulated in this urban villa, which was home to the Barge family (Prof. Barge was the Rector Magnificus of Leiden University from 1937-1938) for nearly 100 years.
