Though it welcomes both freighters and cruise ships, it is of modest size and easily explored.  Parking near its center, we spent the day touring its outdoor highlights; the first of these was the fine City Gardens, harboring a pond, sculptures and an excellent variety of floral and plant displays.  Our second stop was the city's historic Citadel, a British naval fortress during the 18th and 19th Centuries that overlooks Halifax and its waterways.
