## Marker with an Information Window

Now that we have a marker on the map, we can add an information window.

There are three basic things to pay attention to:

- Create content for the information window
- Create the `google.maps.InfoWindow`
- Add a listener so that a click event on the marker causes the information window to open

These steps are shown below:

    /* Create content.  Here we are concatenating strings together with the JS "+" operator */
      var statue_info = "<strong>John Harvard Statue</strong><br/>" +
          "3 Lies of Harvard";

      /* Create the InfoWindow object; note we pass in the content */
      var statue_infowindow = new google.maps.InfoWindow({
          content: statue_info
      });

      /* Create the marker (we've seen this before) */
      var statue_marker = new google.maps.Marker({
        position: statue_latlng,
        map: harvard_yard_map,
        title: 'John Harvard Statue'
      });

      /* Create the listener so that the info window opens when the marker is clicked */
      google.maps.event.addListener(statue_marker, 'click', function() {
        statue_infowindow.open(harvard_yard_map,statue_marker);
      });
