Question: What was destroyed in St. Patrick's Parish on July 30, 1916?
Context: St. Patrick's Parish and Buildings is a historic church on Grand Street, Ocean and Bramhall Avenues in Jersey City, Hudson County, New Jersey, United States.  The stained glass windows in the church were destroyed in the Black Tom explosion of 1916. St. Patrick's Roman Catholic Church on McCaul Street in Toronto, Ontario, Canada, is the church for the city's fifth oldest Roman Catholic parish.  St. Patrick subway station nearby and the adjacent St. Patrick Street were named after the church.  St. Patrick's is the home of the Canadian National Shrine of Our Mother of Perpetual Help.  The German-speaking Catholic community in Toronto holds services in the church as well. St. Patrick's blue is a name applied to several shades of blue associated with Saint Patrick and Ireland.  The colour blue's association with Saint Patrick dates from the 1780s, when it was adopted as the colour of the Anglo-Irish "Order of St. Patrick".  In British usage, it refers to a sky blue used by the Order of St. Patrick, whereas in Irish usage it is often a dark, rich blue.  While green is now the usual national colour of Ireland, St. Patrick's blue is still the official colour of state.  St. Patrick's blue is still found in symbols of both the state and the island. The Centre for Arts, Media, and Technology at St. Patrick Catholic Secondary School (also referred as SPCSS, St. Pats, St. Patrick, St. Patrick C.S.S. or Pats) is a Roman Catholic high school located in Toronto, Ontario, Canada as part of the Toronto Catholic District School Board.  It is dedicated to Saint Patrick of Ireland and St. Marguerite Bourgeoys, the founder of the Congregation of Notre Dame.  One of Toronto's oldest schools, St. Patrick's used to be an elementary school founded in 1852 until 1983 and turned into a secondary school which opened in 1986 on D'Arcy Street (now the Toronto District School Board's Heydon Park Secondary School).  Since September 1989, St. Patrick had been moved from downtown Toronto into the former Lakeview Secondary School (also owned by the TDSB) in Toronto's east end.  The motto for St. Patrick is "Amor Christi nos impellit" which translates to English as ""The Love of Christ Impels Us"". St. Patrick's Island Park (also simply known as St. Patrick's Island) is a 31-acre public park on an island at the confluence of the Bow and Elbow rivers just northeast of Downtown Calgary.  St. Patrick's Island is one of Calgary's oldest parks.  Its development as a public space began in the 1890s, gaining momentum as an important public space in the Calgary inner city with the construction of a bridge to the island in the early 1900s.  Throughout the decades, the island has been transformed, playing host to a campground in the 1960s, to being the host of squatters for much of the period from the 1980s to the 2000s.  For several decades, the island was connected to Calgary's undesirable East Village neighbourhood by a steel and wooden bridge.  However, in the late 2000s the Calgary Municipal Land Corporation began a redevelopment of the East Village, with a particular focus on redeveloping St. Patrick's Island into a full-fledged city park with programmed activities and physical access to the Bow River.  After years of construction, the newly redeveloped St. Patrick's Island Park opened to the public in July 2015, along with the new George C. King Bridge which connects the island park with both the East Village to the south and Bridgeland to the north. The St. Patrick's Parade Day in Scranton is one of the largest Saint Patrick's Day parades in Northeastern Pennsylvania.  It is held in Scranton, Pennsylvania every year on the Saturday of the weekend before St. Patrick's Day - even if St Patrick's day falls on a Saturday or Sunday.  For Example, in 2013, St. Patrick's Day was on a Sunday, and the Parade was held on the Saturday of the previous weekend - March 9 St. Patrick's Market is one of three public markets created in Toronto in the 19th century along with St. Lawrence Market and St. Andrew's Market.  The lot at what is now 238 Queen Street West (at John Street) was designated for a public market for St. Patrick's Ward in 1836 when D’Arcy Boulton bequeathed the property to the city with the express provision that it was to be used forever as a public market.  The original market building, a two-story structure with a tower, was built in 1854.  The current single story structure was built in 1912, after the previous structure was destroyed by fire, and was leased from 1929 or earlier to A. Stork & Sons, a live poultry slaughterhouse which offered "fresh killed poultry and cut up chickens" for sale on the premises.  Stork & Sons closed in the 1980s and, in 1988, the city signed a 50-year lease with Market Inc. to host a "exciting retail mini food market" with "an ambiance similar to the St. Lawrence Market", including a bakery, and stands selling meat, seafood, fruit, vegetables and "food stands with prepared and unprepared meals within its market". Saint Patrick's Church is a Catholic parish in the Archdiocese of Dubuque, and is located at 15th and Iowa Streets, Dubuque, Iowa, United States.  The church and rectory were included as contributing properties in the Jackson Park Historic District that was listed on the National Register of Historic Places in 1986.  St. Patrick's Church is located two blocks away from St. Mary's Church.  The reason for the close proximity of the two parishes was that St. Mary was originally built for service to German families of Dubuque, and St. Patrick's provided services for the Irish settlers to Dubuque. The St. Patrick's Society of Montreal (French: Société Saint-Patrick de Montréal) is the oldest fraternal organization in Canada.  In existence since March 17, 1834, it predates the Société Saint-Jean Baptiste by three months.  The St. Patrick's Society continues to be a leader in Montreal's Irish community, organizing such annual events as the St. Patrick's Ball, the St. Patrick's Luncheon, and the St. Patrick's Society's annual Christmas concert.  The Society's current President is Scott Phelan. The Black Tom explosion on July 30, 1916, in Jersey City, New Jersey, was an act of sabotage by German agents to destroy American-made munitions that were to be supplied to the Allies in World War I.  This incident, which happened prior to American entry into the war, is also notable for causing damage to the Statue of Liberty.
