You cant do that in normally, but you can do this using the i18ntemplate function https://github.com/revel/revel/blob/master/template_functions.go#L170

Steve thanks a lot! But I do not figured out to make it works (always ending up on the "template not found" error). I ended on writing my own function, I copy it here if can be useful for someone else:

revel.TemplateFuncs["external_html"] = func(a interface{}) template.HTML {
        htmlGenerated := ""

        path, err := os.Getwd()

        if err != nil {
            log.Fatal(err)
        }

        path = path + "/app/views/external/html/" + fmt.Sprint(a) + "/"

        files, err := ioutil.ReadDir(path)

        if err != nil {
            log.Fatal(err)
        }

        for _, f := range files {
            if !f.IsDir() {
                data, err := ioutil.ReadFile(path + f.Name())

                if err != nil {
                    log.Fatal(err)
                }

                fmt.Println(string(data))
                htmlGenerated = htmlGenerated + string(data)
            }
        }

        return template.HTML(htmlGenerated)
    }
}
