Vatnsstígur 16–18 is a residential tower located in downtown Reykjavík, Iceland. It is a part of a larger project called "shadow district" (Icelandic: Skuggahverfi) under phase 2. This tower is the tallest residential tower in Reykjavík, standing tall. Construction of phase 2 was delayed due to the financial crisis in 2008, and therefore was not completed on schedule.
