Danvers is a town (and census-designated place) in Essex County, Massachusetts, United States, located on the Danvers River near the northeastern coast of Massachusetts.  Originally known as Salem Village, the town is most widely known for its association with the 1692 Salem witch trials.

The Liberty Tree District is a historic district encompassing a collection of six mid-scale commercial buildings between the Downtown Crossing area and the Theater District of Boston, Massachusetts.  They are clustered around the corner of Washington and Essex Streets, on the edge of the area known in the 20th century has Boston's Combat Zone, or adult entertainment district.  The area is historically significant as the site in the 1760s of the Liberty Tree and the Liberty Tree Tavern, a focal point of colonial discontent against British rule.  This significance is reflected in a carved relief on the Liberty Tree Block, a brick commercial block built in 1850 at the corner of Washington and Essex.  The building was designated as a Boston Landmark by the Boston Landmarks Commission in 1985. North Shore Square is a 621192 sqft shopping mall in Slidell, Louisiana.  The mall is the largest mall on the Northshore of Lake Pontchartrain, fifth largest in the New Orleans area and the 11th largest in Louisiana.  The mall is home to two anchor stores, Dillard's, and At Home, as well as approximately 23 other stores.  All the anchor stores are on one level.  The mall did not flood during Hurricane Katrina and experienced no serious damage.  The mall formerly had Mervyns as an anchor store, but closed shortly after the storm when Mervyn's pulled out of the Louisiana market.  The store was eventually replaced by Burlington Coat Factory, which is now closed due to corporate downsizing.  JCPenney closed on July 31, 2017.  The mall has struggled partially due to increased internet-based sales as well as an open-air shopping center located on the opposite side of town, to which it lost some of its tenants.  Following a nationwide trend, the mall's future is uncertain as many former mall-based stores have either closed completely or downsized nationally, and enclosed shopping malls across the country are challenged by new consumer trends and shifting paradigms.

The Christown Spectrum Mall's anchor stores are JCPenney, Costco, SuperTarget, Walmart Supercenter, Big 5 Sporting Goods, Dollar Tree, PetSmart and Ross Dress for Less.  When the JCPenney was added back to the mall, access to PetSmart, Target, Dollar Tree and Ross Dress for Less was cut off from inside, making only JCPenney, Costco, Big 5 Sporting Goods, and Walmart accessible from the inside.  Christown Spectrum Mall also has a Walgreens and a Harkins Theatres 14 as out-parcel anchors.
