Heritage
The property on which the school stands was given to John
Talbot in 1732 as a land grant from Lord Baltimore. For almost 175 years
individual families lived on this property and farmed the land. In
1906, the Mt. Calvary Episcopal School for Boys in Baltimore City bought
the property and relocated the school changing its name to the
Donaldson School for Boys. As a result of financial losses caused by the
Great Depression, the school was forced to close in 1933. The Sisters
of Notre Dame de Namur purchased 180 acres of property and the original
buildings in 1934 for forty thousand dollars and authorized the opening
of a junior high and high school for girls. In 1941, the Sisters opened
the elementary school known as the Julie Billiart Country Day School
named after the foundress of the Sisters. These students were housed in
St. Margaret's Hall and in the present cafeteria, two of the original
cottages of the Donaldson School. In 1958, the name of the school was
changed to Trinity Lower School.
Four additions were successfully made to the original
cottages of the Donaldson School to complete the Primary School building
as it stands today. In June 1972, the girls' high school was closed and
the high school building was leased to the elementary school. This
building was designated as the Middle School. When the high school
called Trinity Preparatory School closed, the primary and middle schools
became officially known as Trinity School and were subsequently
incorporated.
Ownership
In the spring of 1996, Trinity formulated a strategic plan
for the future development of the school. This plan called for the
construction of a new middle school, improved and expanded roads,
sidewalks, parking areas, and athletic fields. Included in the plan was
the renovation of St. Lidwine's Hall, the former middle school building,
to be used for administrative offices, art and physical education.
A milestone for Trinity was reached in the spring of 2001,
when the Trinity School Board of Trustees purchased the school and the
property from the Sisters of Notre Dame de Namur. An Affiliation Plan is
attached to the Purchase agreement, ensuring the preservation of the
mission, philosophy and long-standing relationship between Trinity and
the Sisters of Notre Dame de Namur.
In September of 2002, the new middle school building was
officially opened and was dedicated and named St. Julie Hall in November
of that year.
The latest major upgrade took place in 2004 when the
Kindergarten Cottage was rebuilt to house 2 classrooms for full day
kindergarten program. In addition, the entire building was renovated and named
St. Joseph Hall.
In September of 2009, Trinity School opened its doors to 3-year old and 4-year old students in the Preschool and Pre-Kindergarten.
