Beauty's Castle than a functioning fortress. The designer also altered other details to give a more substantial feel to the iconography. When the club rebuilt the west stand of the Boleyn Ground (construction finished 2001–02) the "castle" from the redesigned badge was incorporated into the structure at the main entrance to the ground. A pair of towers were prominent features of the ground's appearance, both bearing large club badges. A new badge was introduced following the end of the 2015–16 season, when the club moved into the Olympic Stadium. It removes the Boleyn Castle due to the club moving away, leaving just the crossed hammers, which the club says is inspired by the crest before and during the career of Bobby Moore. The word "London" was introduced below to "establish the club firmly on the international stage", and the more minimalist approach is to give a "strong statement that is instantly West Ham United". The shape of the crest is that of the hull of , the first ironclad warship in the Royal Navy, which was built by Thames Ironworks. Colours The original colours of the team were dark blue, due to Thames Ironworks chairman Arnold Hills being a former student of Oxford University (see Oxford blue). However, the team used a variety of kits including the claret and sky blue house colours of Thames Ironworks, as well as sky blue or white kit. The Irons permanently adopted claret and blue for home colours in 1903. One story suggests that Thames Ironworks right-half Charlie Dove received the Aston Villa kit from William Belton, who was a professional sprinter of national repute, as well as being involved with the coaching at Thames Ironworks. Belton had been at a fair in Birmingham, close to Villa Park, the home ground of Aston Villa and was challenged to a race against four Villa players, who wagered money that one of them would win. Belton defeated them and, when they were unable to pay the bet, one of the Villa players who was responsible for washing the team's kit offered a complete team's "football kits" to Belton in payment. The Aston Villa player subsequently reported to his club that the kit was "missing." This, however, is often disputed. Thames Ironworks, and later West Ham United, retained the claret yoke/blue sleeves design, but also continued to use their previously favoured colours for their away kits. Supporters,
