Amongst the Top-5 Musts when visiting Brussels. Excellent archeological remains of the Coudenberg Palace provide visitors with glimpses into royal life of the 15th and 16th centuries.
A very interesting introductory film of about five to ten minutes starts the journey by inviting visitors into the history and landscape of the former palace. Exploration of the subterranean remains of the Chapel and Great Banqueting Hall await.
Well-signed in English, French, German, and Nederlands, the information provides wonderful context. A free app that guests access on their phone provides additional information, with a few entries having brief, recorded audio information. Worth a half day for lovers of history and archaeology.
I combined my visit with one to the BELvue Museum, aboveground and thoroughly enjoyed it as well.
