In 1864, the year after Le Lacheur's death, it was resolved to build the first Protestant church in Costa Rica. It was made of pre-fabricated iron, was carried to Costa Rica by Le Lacheur's son John and was assembled in San José as the "Church of the Good Shepherd", see of the Episcopal Church of Costa Rica (Anglican faith). It became unofficially known as the 'Iron Church'. When it was rebuilt in 1937 with more traditional materials, a memorial plaque was erected to Le Lacheur with an inscription which includes the phrase ""by whose exertions public Protestant worship was established in this Republic"".
