You can't miss it, right in the beautiful historic center of Middelburg. Here, the imposing Abbey Tower de Lange Jan rises proudly above the many monuments in Middelburg. You should not miss the climb. It takes a bit of climbing, 207 steps to be precise, but the view is worth this effort. The tower of the Lange Jan is 90.5 meters long (belongs to the top 10 tallest towers in the Netherlands). On clear days you can even see the surrounding Zeeland islands from the Lange Jan. http://www.langejanmiddelburg.nl/
