+# European Co-location Tier Index
+
+The European Co-location Tier Index serves as the authoritative map of commercial convergence across key European markets. Utilizing the [Retail Co-location Methodology](topic-co-location-methodology.md), the index identifies the highest-value commercial nodes based on the convergence of Primary Targets (IKEA) with essential Secondary (Leroy Merlin, Makro) and Tertiary (Healthcare, Higher Education) anchors.
+
+## Market Scarcity and Institutional Validation
+
+Achieving a high-tier designation requires the simultaneous convergence of multiple independent, capital-intensive operators within a restricted geographic radius. These top-tier sites represent the apex of commercial validation, analogous to a 3-star Michelin rating: indicating a market node so exceptionally structured that it is "worth a special journey" for institutional capital deployment.
+
+## Regional Overview
+
+The following table summarizes the distribution of the highest-quality nodes across the initial European markets in scope. For exhaustive, rank-ordered lists, refer to the country-specific indices.
