Hi Denis, thanks for your answer. addBuilding is a custom function that creates a vector on the vector layer with a special icon. I already use vectors instead of markers, apologies for my unclear description. I do have a vector layer and place different vectors of OL.Features.Vector on it. But I can't get the clustering work so far. The only difference between your code and mine is that you add 'autoactivate: true' to your Cluster constructor, I don't know if this is mandatory for the clustering to work, I will test it on Monday. Any other comments on that? I really appreciate your fast and competent answer!

What is addBuilding function? I'm not sure about cluster strategy may be used with markers. I'm prefer to use features, because markers are deprecated: <html><body>
  <div id="mapdiv"></div>
  <script src="http://openlayers.org/dev/OpenLayers.js"></script>
  <script>
    map = new OpenLayers.Map("mapdiv");
    map.addLayer(new OpenLayers.Layer('', {isBaseLayer: true, maxExtent: new OpenLayers.Bounds(-200,-200,200,200)}));

    var buildingLayer= new OpenLayers.Layer.Vector("Buildings", {maxExtent: new OpenLayers.Bounds(-200,-200,200,200),
        strategies: [new OpenLayers.Strategy.Cluster({autoActivate: true, distance: 100})]
    });

    map.addLayer(buildingLayer);
    buildingLayer.addFeatures([new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(-50.126,36.755)),
    new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(-100.196,43.215)),
    new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(-150.556,56.615)),
    new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(-170.423,35.510))]);
    map.zoomToMaxExtent();
