Very large European Garden Spider, South of Netherlands
This is a very common spider in the Netherlands. When walking through any bushes or fields, you'll likely walk into a few dozen of these webs. This one, however, is by far the largest European Garden Spider that I have ever spotted. Wikipedia mentions they grow up to about 2cm, but I remember this one being significantly larger.
