Attending Plenary

Published 01/09/2020   |   Last Updated 16/07/2021   |   Reading Time minutes

In line with recent changes to the Welsh Government’s Alert Levels, the Senedd building has been opening in phases. Our first phase was to open the Public Gallery for observing Plenary. Next and over the summer, we are proud to host the closing presentation of Undo Things Done, Sean Edward’s exhibition commission for Cymru yn Fenis / Wales in Venice 2019.

The capacity of the Senedd building will be limited and the Senedd will be open only for pre-booked visits

We’ll share our plans of opening the buildings on our social media and website, so remember to follow us there if you don’t already. 


You are welcome to attend the Senedd building to observe Plenary in the Siambr, which is the Senedd's debating chamber. The Public Gallery is fully accessible: including a space for wheelchairs, and the live broadcast of the session is viewable on a screen immediately in front of you, and an audio feed is available with headsets provided. 

Plenary is the full meeting of all 60 Members of the Senedd, which takes place in the Siambr and online on Tuesday and Wednesday afternoons. Plenary begins at 13.30 and finishes at 17.00 although this can sometimes vary.  

You can find out what will be discussed in Plenary by viewing the Plenary agenda for that meeting. Copies will be available at the information desk. For further information and enquiries please contact us.
