Prior to 1817, a
 courthouse serving both Washington and St. Tammany Parishes was located
 near Enon in Washington Parish in an area known as "Washington Fields."
 Records indicated that some soldiers were stationed there for the War 
of 1812.

According to a publication of the Louisiana State Bar Association entitled "Louisiana’s Historic Courthouses: A Look at the Past and the Present,"
 (Published in 2016) The St. Tammany Parish courthouse sprang from 
legislation signed by Louisiana's first governor, William Charles Cole 
Claiborne in 1813. The legislation called upon a local committee to  
locate  a  courthouse site  "within three miles of the center of St. 
Tammany Parish,  which  at  that  time  consisted  of  Washington  
Parish,  St.  Tammany  Parish and the portion of Tangipahoa Parish east 
of the Tangipahoa River."
Following
 those directions, the group established the first courthouse near the 
banks of the  Bogue Chitto River near Enon on property owned by Judge 
Thomas C. Warner, who was the first parish judge in St. Tammany  Parish.
The
 Bar Association's Journal went on to explain that four years after 
establishing the courthouse near Enon, another group was given the 
assignment of moving the parish seat. "The  Claiborne Company had 
purchased a portion of the Kleinschmidt Spanish land grant in 1813. In 
exchange for the commission naming the Town of Claiborne as the parish 
seat, the Claiborne Company offered some of its land and agreed to build
 a courthouse and jail for the parish, free of charge."
"Robert
 Layton told them (the group seeking a parish seat) that he'd build a 
courthouse if they made Claiborne the parish seat," said retired Judge 
Steve Ellis, a parish historian. This resulted in the second St. 
Tammany Parish courthouse being built in the Town of Claiborne  just 
east and across the river from Covington. It cost around $20,000 to 
build.
That building, built in 1818, currently stands across the driveway from the Chimes Restaurant near the Bogue Falaya River. The structure was completed and opened for business on April 12, 1819.

 However,
 the bar journal account noted that "within  10  years  of  the  
erection of the 1819 Courthouse, the Police Jury determined that the 
courthouse should be moved  to  Covington,  previously  known as the 
Town of Wharton."
On June 5, 1837, the Police Jury purchased Lots 12-15 on the corner of Boston and New Hampshire Streets in Covington for use as a courthouse site, the bar journal stated. 
The
 1819 Courthouse was eventually sold and used as a private residence and
 Catholic seminary. In  the  late  1800s,  a  hotel  known  as  the  Claiborne Cottages was built next to the former 1819 Courthouse. Those cottages were destroyed by fire in the early 1900s.   
The
 parish seat was moved from Claiborne to Covington in 1838. A courthouse
 was built on the corner of Boston St. and North New Hampshire St. In  
1884,  however, the  Police  Jury  voted  to demolish  the  courthouse  
located  at  that location. "During the demolition and rebuilding 
period, Covington Town Hall  was  used  as  a  courtroom.  The  new  
courthouse opened two years later in 1886 and was used for 73 years, 
according to the bar journal account.
 The
 structure pictured above at that location was built in 1896, with the 
cornerstone of that building pictured below, as it looks preserved as a 
monument in front of the old courthouse site at the northeast corner 
Boston St. and New Hampshire St.  
Here are some additional pictures of that 1896 structure.

"The
 completion of the Lake Pontchartrain Causeway in 1956 magnified the 
need for a larger facility to conduct the parish’s business," the Bar 
Association article went on to say. "In 1959, the parish decided to 
build a new courthouse, completed in 1960. Within the year it took to 
complete the new courthouse, court was held in the gymnasium of the 
Jefferson Avenue  grammar  school.  The new courthouse shown below was 
opened in 1959 in the same location as the previous courthouse. It 
featured a jail on the third floor.
Here is the printed program for the ceremonies opening the new courthouse on June 1, 1960.
The
 police jury held a number of committee meetings about what to do about 
the growing space problems in the courthouse building. 
They finally decided, despite objections, to build a new courthouse down near Interstate 12. 
The
 courthouse stayed in Covington, however, after some legal action by 
city officials noting that the courthouse had to be in the parish seat. 
For
 a brief time, in an effort to provide more space, there were a couple 
of courtrooms and judges offices in the building where the Southern 
Hotel is located today. It served as Parish Administrative Offices for several years, complete with police jury meeting room and offices for various parish agencies. 
The
 parish chose to ignore the city's objections and built an office 
facility on Koop Drive off La. 29 near Interstate 12, moving its main 
administrative offices and several key departments to that location. In 
1996, efforts resumed to build a bigger courthouse, but within the 
boundaries of the City of Covington. The old P&W Salvage facility on
 Jefferson Avenue was considered.
"The
 1960 courthouse was used until the St. Tammany Justice Center opened in
 2003, which brought together many of the parish’s offices that were 
scattered throughout the city," according to the Bar Association 
article. Planning for the massive $64 million structure began in the 
year 2000.
"The
 St. Tammany Parish Justice Center, unlike  any  courthouse  in  
Louisiana,  is  a 312,000-square-foot structure containing 22,000 cubic 
yards of concrete and 25,000 St. Joe bricks and housing 12 courtrooms," 
said the article. Here are some photographs of that building.
