Victoria, the capital of British Columbia province in Canada, is celebrating its 150th year. One might think that the much larger mainland city of Vancouver would be the capital, but it was late to the game, being incorporated in 1886.
Few decent-sized North American cities manage to maintain a consistent architectural theme, though downtown Santa Barbara's Spanish Colonial architecture comes to mind. Victoria doesn't have a consistent theme, but in recent years some large, new structures have picked up the chateau style of the city's famous Empress hotel. As the link indicates, the Empress was built by the Canadian Pacific transportation company, being opened in 1908 and expanded since then.
Two recent structures echoing the Empress' chateau theme are the Delta Victoria Ocean Pointe Resort and Spa and the Hotel Grand Pacific located nearby facing the Inner Harbour.
