Both of the modern sculptures above and left are located on Rue de la Loi, Law Street, in front of the Justus Lipsius building, where the European Council meets at least twice every 6 months according to the European Council website. The European Council is only one of several important European institutions which has led to Brussels being called the de facto capital of Europe.
Yesterday, I posted a picture of the monolith (left) that has the quote, May all peoples thrive and prosper, listed in 23 languages. Donated in 2008 by the Minister of Culture of the Republic of Slovenia as a lasting symbol of Slovenia's European Union (EU) Council Presidency that year, the 23 languages were those spoken by EU member states. Slovene is listed first, followed by the other languages in an order designed to follow the flow of the stone's vein. Today, one would need to add Croatian, since Croatia joined the EU in 2013.
