Question: The Barbarossa Chandelier was installed under the cupola in the Roman Catholic church in what state?
Context: Church of St. Casimir (Lithuanian: "Šv.  Kazimiero bažnyčia" , Polish: "Kościół Św.  Kazimierza" ) is a Roman Catholic church in Vilnius' Old Town, close to the Vilnius' Town Hall.  It is the first and the oldest baroque church in Vilnius, built in 1618. [1] The construction of the church began in 1604 in memory of the holy prince Saint Casimir: it was built by the Jesuits with funding by the Great Chancellor of the Grand Duchy of Lithuania Lew Sapieha.  It is traditionally assumed that the corner stone (which can be seen on the façade wall) was pulled into the city by procession of 700 Vilniusites from the Antakalnis hills.  The construction was finished in 1616, and the interior design completed in 1618.  The Church of St. Casimir is one of the earliest exemplary Baroque buildings in the city, designed along the line of the famous Il Gesù church in Rome (Church of the Gesù).  It was apparently designed by Povilas Bokša, and the construction was supervised by Jan Frankiewicz, a pupil of architect Giovanni Maria Bernardoni.  In the middle of the 18th century the church was reconstructed by architect Tomas Žebrauskas.  Under his supervision a stepped lantern cupola with a crown was erected.  This large and impressive cupola is unique in the entire region of the former Grand Duchy of Lithuania.  Under Russia's occupation the church of St. Casimir was converted into a Russian Orthodox church.  In 1915 Vilnius was occupied by the Germans and the church was converted into the Evangelical Lutheran prayer house of the Vilnius Garrison.  In 1919 the church of St. Casimir was returned to the Catholics, but was damaged again during the Second World War, closed down and in 1963 converted into a Museum of Atheism.  The church was reconsecrated in 1991. St. James the Less Roman Catholic Church, also known as St. James and St. John's Roman Catholic Church, is a historic Roman Catholic church located at Baltimore, Maryland, United States and was one of the earliest neighborhood parishes established in the central city (1833).  It is a High Victorian Gothic influenced brick structure with Romanesque Revival overtones built 1865-67.  It has a tall central tower and featured an ornate interior with marble sculpture and murals.  The church is 184 feet long, 65 feet wide, and the ceiling is 51 feet from the floor.  The steeple, at 256 feet, is the second tallest church tower in the city (next to First and Franklin Street Presbyterian Church at West Madison Street and Park Avenue, in Mount Vernon-Belveere neighborhood, constructed 1875), which dominates Old East Baltimore.  The cross surmounting the spire, is 10 feet tall.  There is a peal of four bells in the tower, the largest weighing 5000 pounds, cast by McShane of Baltimore, in 1885.  The tower clock was installed during the same year.  The magnificent and priceless 25 foot-high Mayer windows were installed in 1891.  The church is an early work of George A. Frederick (1842-1924), a prolific and prominent architect in Baltimore who designed various buildings in the city including the Baltimore City Hall in 1875.  The interior features three large interior murals painted about 1886 by the German-born artist William Lamprecht and marble sculpture work by the Baltimore sculptor Joseph Martin Sudsburg.  In 1966, the neighbouring parish of St. John the Evangelist was closed, and the new parish of St. James and St. John, was formed, the congregation worshipping at St. James.  The parish was dissolved around 1986, and the former St. James Church was sold to an evangelical church.  Most regrettably, the church has been stripped of its windows, altars, marble communion rail, pipe organ, and other artifacts, and the church has been whitewashed, destroying its beautiful and historic murals.

Mexican Catholic Apostolic Church Spanish: "Iglesia Católica Apostólica Mexicana" (ICAM) was a church founded in 1925 to bolster revolution and machinate a schism from the Catholic Church in Mexico with the support of the Regional Confederation of Mexican Workers (CROM) and Mexican President Plutarco Elías Calles' approval.  President Álvaro Obregón and his successor Calles, as well as other politicians, wanted the revolutionary government to restrict and terminate the Catholic Church in Mexico.  In February 1925, armed intruders calling themselves "Knights of the Order of Guadeloupe" occupied the church of María de la Soledad in Mexico City where , a Freemason and former Catholic priest, proclaimed himself the future patriarch of a new national church; parishioners attacked the interlopers and rioted the next day; similar riots were incited when other churches in Mexico were occupied by armed intruders that month.  These armed intruders occupying churches induced fear of anti-Catholic persecution that led to the formation of the National League for the Defense of Religious Liberty (LNDLR) a militant Catholic defense organization.  Official favoritism of a national church enraged revolutionaries who saw this as a "violation of state "laicidad "" with potential to faction the revolution, so Calles stopped his support of after about 3 months.  Nevertheless, the government failed in 1925 to orchestrate Pérez's consecration by a visiting Eastern Orthodox bishop, but in 1926, North American Old Roman Catholic Church Bishop Carmel Henry Carfora consecrated Pérez, Antonio Benicio López Sierra, and Macario López Valdez as bishops.  In 1927, López Sierra established an church in San Antonio, Texas, where Archbishop Arthur Jerome Drossaerts, of the Roman Catholic Archdiocese of San Antonio, called the "cismáticos " (Spanish for schismatics) "designing proselytizers of the sects supported by Calles and the Mexican government, that archenemy of all Christianity;" and in 1929, López Valdes established an church in Los Angeles, California.  Pérez moved his cathedra to San Antonio in March 1930 but in April 1931, Pérez returned to Mexico City.
