Over 50 museums in one evening. And every guest plans their own night.
At the Long Night of Museums Hamburg, over 50 museums, exhibition venues and memorials open their doors at the same time. The website brings together the entire programme, supports personal tour planning and helps visitors find their way between the different venues.
Since 2023, we have provided technical support for the platform and developed it further together with Museumsdienst Hamburg.
Many museums maintain a shared programme.
The content of the Long Night is created in a decentralised way. Each participating museum maintains its opening hours, events, images and other information via its own protected account.
Museumsdienst Hamburg checks and coordinates the submitted content and decides when the programme appears on the website.
This information is the basis for the programme overviews on the website, with filters by topic, museum, time and language, and for the museums' detail pages. Guests' personal night plans are built on it as well.
The system therefore supports two distinct phases: before the event, many participants work on the programme together. During the night itself, guests use the website on the go to find events and navigate between the venues.
Keep the platform running, develop it in targeted steps.
Technical foundation
We moved the website into the seeforfree TYPO3 installation, which we have been supporting since 2023 with Composer, version control and separate environments for development, testing and live operation.
TYPO3 upgrade
We upgraded the shared installation to TYPO3 12 in two steps, via TYPO3 11, carrying over the museums' custom input forms and data structures.
Decentralised maintenance
The input forms help the venues provide all the required information and give guidance on image descriptions.
Planning for visitors
We revised the personal night planning in 2025: selected events stay marked when switching between pages and can be removed again with one click. A short message confirms each selection.
Accessibility revised
In 2025, we checked and revised navigation, forms, contrasts and interactive components. The current status is documented in the publicly available accessibility statement.
Find museums, plan the night.
The programme becomes your own night.
Visitors can save events to their personal selection and sort them by time. This creates an individual night plan that they can download as a PDF and open on their smartphone during the event.
The selection is stored only in the visitor's browser and lasts for the current browser session. The PDF is also generated directly in the browser. The selection is neither analysed nor stored on the server. No registration is required.
Museums and connections at a glance.
The map takes the locations from the centrally maintained museum data, so the information needed to display the museums does not have to be entered again in a separate map system.
Layers that can be switched on and off show shuttle buses, boat connections and bike stations. Guests can see which venues are close to each other and which connections suit their plans.
The project in numbers.
Support for similar projects.
Bring together many participants on one platform?
If different locations or departments need to maintain their own content, we work out responsibilities, approvals and the shared data structure with you. On that basis, we plan the implementation – as further development of your existing website or as a new project.
