Private Tours

In addition to the free walk-in tours, we offer private tours for groups. These guided tours go deeper into the history of the building, but also offer the opportunity to learn more about astronomy in general.

Within the walls of the Old Observatory there is a rich history. Although the building is now used for quite different purposes than when it was opened in 1860, the historical value of the building is immediately perceptible upon entry. 

A unique experience for young and old alike

Take a group with you to the Old Observatory and let an astronomy student guide you through the building. Learn more about the telescopes, the history of the building and the research in Leiden from then and now.

If the skies are clear, you can look through the telescopes, the same telescopes that great scientists like Einstein, Lorentz, Oort and many others have done observations with!

Options and prices

Due to the limited size of the domes, only fifteen people can enter at the same time. For that reason, we assign one tour guide to every fifteen people of your group. The price per tour guide is fixed. You can choose between two options:

  • A normal tour of 1.5 hours for €90 incl. VAT per 15 people.
  • A shortened tour of 45 minutes for €65 incl. VAT per 15 people.

All guided tours are paid per invoice. When requesting the tour, you can fill in your financial details. You will then receive an invoice with the payment details at the end of the month in which the tour took place. It is not yet possible to pay for the guided tour at the observatory.

Route description

When requesting a tour you can indicate where you want to be picked up by the tour guide. Normally, groups are received at the main entrance of the Old Observatory. The address is Sterrenwachtlaan 11, which can be reached via the Kaiserstraat.

You can also combine your guided tour with a visit to the Hortus Botanicus. You will then have to buy a separate admission ticket at the entrance of the Hortus. This is located on Rapenburg 73. From the entrance of the Hortus it is about a ten-minute walk to the Old Observatory.
