 No trace of Bau having been named "hijo predilecto" of Tortosa in 1966 can be found on the official ayuntamiento web page.Since 1956 until 2018 one of Tortosa colleges was named "Institut Joaquín Bau" (today "Institut Dertosa"), though there was a failed attempt to change the patron in 1983.Bau's biography, in large part a hagiographical compilation of his correspondence from the private archive, was published in 2001; the author defined Bau as a conservative monarchist and played down Carlist threads, ignoring also most controversial episodes from his lifetime.
