Herman Vanderpoortenstadion (pronounced as /nl/), also called Het Lisp (pronounced as /nl/), is a multi-use stadium in Lier, Belgium. It is currently used mostly for football matches and was the home ground of Lierse between 1925 and 2018.[2] The stadium holds 14,538,[3] including 4,311 standing places, 522 business seats, 102 VIP seats and 3 loges.[2] Following the bankruptcy of Lierse in 2018, it is unclear who will be the new tenants.
