Question: Christ Church Lutheran is located in a borough that locally is often referred to as what?

<P0-S0> Manhattan ( , ) is the most densely populated borough of New York City, its economic and administrative center, and its historical birthplace. <P0-S1>  Locally it is often referred to simply as "The City". <P0-S2>  The borough is coextensive with New York County, founded on November 1, 1683, as one of the original counties of the U.S. state of New York. <P0-S3>  The borough consists mostly of Manhattan Island, bounded by the Hudson, East, and Harlem rivers; several small adjacent islands; and Marble Hill, a small neighborhood now on the U.S. mainland, physically connected to the Bronx and separated from the rest of Manhattan by the Harlem River. <SEP> <P1-S0> Christ Church is an Anglican church in the town and seaside resort of St Leonards-on-Sea, part of the Borough of Hastings in East Sussex, England. <P1-S1>  Opened as the town's third Anglican church in 1860 to serve a rapidly developing residential area and to accommodate poor worshippers who could not afford pew rents at the fashionable St Leonard's and St Mary Magdalene's Churches, the original building was superseded by a much larger church built next to it between 1873 and 1875. <P1-S2>  Prolific ecclesiastical architect Sir Arthur Blomfield's simple Gothic Revival design forms a landmark on one of St Leonards-on-Sea's main roads, continues to serve a large area of the town (including the former parish of the now closed St Mary Magdalene's Church) and maintains a strong Anglo-Catholic tradition. <P1-S3>  It has been described as Blomfield's "finest achievement in Sussex" and "one of the main centres of Anglo-Catholic worship in Southern England". <P1-S4>  The interior fittings are the best of any church in the borough, and the design has been called one of Blomfield's most successful. <P1-S5>  St John the Evangelist's Church, founded as a daughter church nearby in 1865, also continues to thrive as a separate parish church. <P1-S6>  English Heritage has listed Christ Church at Grade II* for its architectural and historical importance. <SEP> <P2-S0> The Old Christ Church Lutheran was a former Lutheran congregation in North America founded in 1750 after breaking off from Trinity Lutheran Church. <P2-S1>  The two congregations reunited in 1784 as The United German Lutheran Churches in New York City, but still referred to as Christ and old Trinity. <P2-S2>  The two united congregations began sharing the St. Matthew's Church structure in 1822 while keeping separate names. <P2-S3>  This continued until the name ceased in 1838 and the congregation was just called the Evangelical Lutheran Church of St. Matthew. <P2-S4>  The present New York Lutheran church of the same name, Christ Church was founded much later after the Old Christ Church name was no longer used. <SEP> <P3-S0> Christ Church Lutheran is an Evangelical Lutheran Church in America church located near Union Square in Manhattan, New York City at 123 East 15th Street at Irving Place, in the Seafarer and International House. <P3-S1>  The congregation was founded as the Evangelical Lutheran Church of Christ in 1868, and has had four premises in its history.
